Hi Pavel. Thanks for reporting this. I confirm your observation. For example, when I compile argp's example #2 (http://www.gnu.org/software/libc/manual/html_node/Argp-Example-2.html#Argp-Example-2), the --version option doesn't work. > I guess the problem happens because of DLL's nature. DLLs cannot contain > unresolved symbols, so the DLL has own version of argp_program_version which > is always initialized to NULL. There's no way to override it. Also confirmed. argp.h declares argp_program_version as extern const char *argp_program_version; But gllib/argp-pv.c initializes it as const char *argp_program_version = (const char *) 0 Whether there's a way to override that value by one declared in the user's code, I don't know. Maybe a linker switch? The same problem also applies to argp_program_bug_address, which is also extern const char *. > Is it possible to fix this somehow ?

Could someone with more C or Gnulib knowledge than me comment?
