Modules that load but do nothing

Modules that load but do nothing

[Bart Schaefer]

If you configure --disable-dynamic and then force modules to be linked
by changing config.modules to "link=static", the build will create the
necessary .a file so that the linking phase completes, and loading the
module with "zmodload" will return a zero status; but it is possible in
this case for some modules to load with no features.

The plainest example of this is zsh/pcre, which will compile and link
but fail the V07 test suite.

Are there other such modules?  zsh/regex and zsh/curses, perhaps?  There
are no tests applied to the latter; the former is tested in C02.

I'd suggest that at least we do the following:

diff --git a/Test/V07pcre.ztst b/Test/V07pcre.ztst
index 3a65331..3c25be2 100644
--- a/Test/V07pcre.ztst
+++ b/Test/V07pcre.ztst
@@ -1,6 +1,6 @@
 %prep
 
-  if ! zmodload zsh/pcre 2>/dev/null
+  if ! zmodload -F zsh/pcre C:pcre-match 2>/dev/null
   then
     ZTST_unimplemented="the zsh/pcre module is not available"
     return 0

I was trying to link zsh against musl the other week to test some
unicode 6.1 stuff, and ended up with a terminfo module that didn't
provide echoti or $terminfo. I haven't looked at any tests in relation
to that though.
