4.0.4: Multiple definitions of program_name

[Albert Chin <rpm-list thewrittenword com>]

The IRIX linker complains when created the RPM executables about
multiple definitions of program_name:

This is because program_name is defined in system.h:
  /* Retrofit glibc __progname */
  #if defined __GLIBC__ && __GLIBC__ >= 2
  #if __GLIBC_MINOR__ >= 1
  #define __progname      __assert_program_name
  #endif
  #define setprogname(pn)
  #else
  #define __progname      program_name
  #define setprogname(pn) \
    { if ((__progname = strrchr(pn, '/')) != NULL) __progname++; \
      else __progname = pn;               \
    }
  #endif
  const char *__progname;

Any chance of alleviating these warnings? Maybe the .c file contain
main() of each of the RPM programs could #define PROGNAME_DEFINE
before #include "system.h" and then modify system.h to:
  #ifdef PROGNAME_DEFINE
  const char *__progname;
  #else
  extern const char *__progname;
  #endif

NOTE, the executable is still created. I haven't tested yet though
(rpm --help worked though).
