[PATCH libgpg-error] Add patch to support IBM z/OS

[Sachin T]

Hi,

Apologies for the delayed response.

Thank you for the suggestions. I will look into both options and follow up with a patch once I have a solution prepared.
Regards
Sachin

I think we have something like this also for an older SunOS or so.  The
solution was to explictly reference the symbol for the main code.  I
think this was/is in Libgcrypt but I can't remember.  But no problem if
you already have a solution.

I think it better to put this into configure.ac - this also documents
the need for them.

+case "$build_os" in
+    *zOS*)
+        EXTRA_LIBS_FOR_BUILD=-lzoslib -lzoslib-supp <lib_path>/celquopt.s.o
+        ;;

Is there any standard <lib_path> or can this be figured out at configure
run time?

Another option would be to add it to autogen.rc and extend autogen.sh
with a --build-zos option like we did for Windows.
