I assume you're trying to build libgcc prior to having built & installed 
glibc?

IIRC, the right way to do this is to first use glibc's install-headers 
target to get the header files installed, then you can build gcc.

Regardless, I don't offhand see a need for unistd.h in that file.  I'll 
remove it during the next development cycle.
