   4 Subject: [PATCH] compat: don't re-define program_invocation_short_name
   5
   6 program_invocation_short_name is defined in errno.h, and its definition
   7 can differ between the various C libraries: glibc defines it as:
   8     extern char *program_invocation_short_name;
   9
  10 while uClibc defines it as:
  11     extern const char *program_invocation_short_name;
  12
  13 So there is not simple solution to know the prototype.
  14
  15 But since it is defined in errno.h, there is no reason to try and define
  16 it ourselves; let's just trust what the header provides.
