Thank you very much.

I think that SIZE_T_MAX is a non-standard macro, and defining it in
system header limits.h violates both ANSI C and POSIX standards. For
example, glibc does not define it.

I think no more testing is needed.

Gzip'ed files are not supported by standard C input/output functions
(i.e. by fopen, fread, fwrite, etc.). Thus, if zlib is not linked on
building glpk, it is impossible to read/write .gz files on the fly; you
should inflate .gz file into a temporary before passing it to glpsol.
