No, the Mac OS X linker is fine. It's giving errors for violations of ANSI C.
You have two functions with the same name; this is an error.

But on ELF systems, only one of the two functions will be active. I.e.
an allocation failure in libshishi will call the xalloc_die from libgss.
You said that this is not what you want.

The clean way is: You want to have two functions of different behaviour,
so give them different names. For example, while compiling libshishi,
add "-Dxalloc_die=shishi_xalloc_die" to the CPPFLAGS, and similarly for
libgss. At the linker level, the two function names will be different,
and all is fine.
