The current AWK based scheme doesn't handle cross compiling.
It assumes that whatever "signal.h" file it finds that has
something like "#define SIG*" in it is the correct one and
then does a bad job at being a C preprocessor to extract
the signals. The only time it would get it right is if the
target architecture has the exact same set of signals the
host architecture does. Coincidentally, my C based scheme
has the same property.
So the new way doesn't change things.

Check out my argument to Bart about why I think the mksignames.c
scheme is no less broken than signames.awk in this regard. I think
there is a good chance that cross compiling was already broken, at
least with respect to finding all the signal names.
(And if this is the case, perhaps the code in mksignames.c
should be stuck into zsh itself, wasting a bit of RAM but
getting it right in all cases.)

I thought that might be it, but:

} - if rlim_t is unsigned
These four are just testing compiler capability, and can be done without
using the cross-compilation options (though I don't know if they ARE done
that way); and as you point out all but
} - if named FIFOs work
can be turned off (or should be) by specifying no dynamic module loading.
Signals are pretty basic to the shell with or without dynamic modules.
Seems to me it should be possible to do this particular thing with just
the preprocessor, rather than needing to compile and execute a program.
use the awk script to generate a bunch of #defines for every possible
signal in the header, feed that through "cc -E ...." and then awk or sed
the output again to extract the stuff zsh needs.

As configure.in contains AC_TRY_RUN statements, it looks to me
unlikely that the zsh build system supports cross-compilation anyway
--- this is specifically warned about in the autoconf manual ---
in which case there's no objection to Matt's patch. Does anyone know
for a fact that zsh has ever been successfully cross-compiled?
FYI, the tests that currently have to be run, rather than just
compiled, are the following. All but the first five are to do with
dynamically linked libraries.
- signed to unsigned casting
- if tgetent accepts NULL
- if rlim_t is quad_t
- if rlim_t is unsigned
- if named FIFOs work
- for ELF binaries
- if dlsym() needs a leading underscore
- if static/shared linking is broken
- if name clashes in shared objects are ok
- whether cross-library links are ok
- for working RTLD_GLOBAL
- if libraries can find symbols in exec
- whether executables can be stripped
- if dynamically loaded libs can be stripped

The trouble is mksignames actually has to run on the target
architecture to generate the appropriate signal names. I don't know
if there's any way of doing that at all with autoconf. Any more
ideas? We could maybe make it conditional on not cross-compiling,
since it does solve the #include problem fairly neatly.

In principle this shouldn't be a problem, except that autoconf 2.13
doesn't seemed to have appeared on any mirror yet. Even then I would
hope $(ZSH_EXEEXT) would just be empty for anyone who needed to run a
previous autoconf (which is supposed just people adding new patches to
the configuration behaviour), which wouldn't be so bad. However, the
patch won't be in pws-8 because of the cross-compilation problem.
(Does anyone know this actually works at the moment?)

It's not a good thing if it won't cross-compile. I didn't use to pay much

sed-like substition on its man page templates!) so I'm feeling sensitive.

[-- Attachment #1: Type: text/plain, Size: 2013 bytes --]
There are two problems with the make system in zsh-3.1.5-pws-7 (and
surely previous versions) when running under cygwin.
1) The makefiles assume they are creating "zsh" and not "zsh.exe." Not
a problem unless you do a "make install" under cygwin.
2) The Src/signames.awk gets confused by cygwin's sys/signals.h since it
defines signal names for multiple platforms (many of which #define all
the signal names to 1).
I fixed #1 by adding AC_EXEEXT to configure.in and using the
corresponding $(EXEEXT) variable where needed in the other makefiles.
WARNING: I imagine you need a fairly recent autoconf to get the
AC_EXEEXT (I tested with version 2.13). You can get it at
http://sourceware.cygnus.com/autoconf/.
I fixed #2 by re-doing the way signames.c is created. Instead of a AWK
script that gets run on a signal.h file, a C program is compiled and
run. This gets it right even if the signal.h file is hard to parse.
My fix for #1 may be controversial because it may break for people who
need to keep using an older autoconf. Is upgrading a problem?
My fix for #2, I think, is a good thing. ;-) I'd do the same thing for
the RLIMIT stuff if cygwin had RLIMIT stuff.
The patch for both is attached (they intertwine).
Please let me know if sending patches as MIME attachments is an
inconvenience (though, pasting a patch file into this little hotmail
edit window may ruin it).
The patch file is generated with cvs rdiff. If you apply it with
'patch', do it as "patch -p1 -E < zsh-patch.txt" in the root of your zsh
tree. "-p1" (p-one, not "el") will strip off the leading "zsh" path
component that cvs rdiff likes to add. "-E" will delete
Src/signames.awk instead of leaving it as a zero length file.
REMEMBER: Src/mksignames.c is a new file, Src/signames.awk gets deleted.
Testing: You might check that "kill -l" prints the same thing before and
after this patch.
