Because gcc is not the only supported compiler?

However, looking at link-warning.h, it seems it only works when the
system uses GNU LD _and_ ELF.  So I'm not sure link-warning.h provides
anything substantial that a Gcc-specific solution wouldn't.  Are there
popular environments that use GNU LD but not Gcc?  Adding support for
cygwin would be useful though.
