GCC supports a
#pragma directive that changes the name used in assembly for a given declaration. While this pragma is supported on all platforms, it is intended primarily to provide compatibility with the Solaris system headers. This effect can also be achieved using the asm labels extension (see Asm Labels).
redefine_extname oldname newname
This pragma gives the C function oldname the assembly symbol newname. The preprocessor macro
__PRAGMA_REDEFINE_EXTNAME is defined if this pragma is available (currently on all platforms).
This pragma and the asm labels extension interact in a complicated manner. Here are some corner cases you may want to be aware of:
#pragma redefine_extnameis always the C-language name.
