Thank you very much for your bug report!

I have no access to macos, so I cannot attain the bug to appear. Most
probably there is something wrong in standard macros feof and ferror
(stdio.h), because the preprocessing errors happen only in lines 319
and 324 where feof and ferror are used. I believe there is a conflict
between system macros and macros defined in glpmps.c.

Please replace glpmps.c by a patched one I am posting (see the
attachment) before compiling the package. The error must disappear.

Note that there is another bug detected in the version 4.2. To avoid it
you need to use 'make LIBS=-lm ...' rather than just 'make ...'. For
more details see:
