ocaml 3.11, Vista 64/cygwin/gcc4

[Jacques Carette]

Has anyone managed to compile 3.11 on Vista 64 under cygwin using gcc4 
[and without flexlink]?

Compilation of byterun/interp.c fails miserably, with most _caml_ 
symbols returning 'undefined reference's. 

Strangely, configure thinks that my system is 32 bits, which is quite 
possibly another source of problems.

PS: I'll soon enough install some flavour of Ubuntu on this machine too, 
which should fix my problems.  But in the meantime, I would still like 
to be able to keep on working!

Is that possible? I believe that flexlink is needed for all Windows ports
(Cygwin included - as in README.win32) as it's used internally to simplify
linking even when creating Cygwin executables.

So that could be related to the above?

Cygwin is 32 bit - so this is entirely correct. When you run Cygwin's bash,
you're in the WOW subsystem and will so the architecture will report itself
as 32-bit (if you look in task manager then you'll see that bash.exe is
starred).

I imagine that there's a reason that you're both building your own OCaml and
also using the Cygwin port specifically but just in case: the MinGW and
MSVC64 builds both definitely work on Vista64...
