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