There are two C pre-processor directives that are used on the
UnixPC, but are ignored by CC.  These are #sccs, and #ident.

Gcc-cpp also properly ignores #sccs, but passes #ident to
the compiler, which then generates a .ident string in the assembly
file.  I do not know if this is the standard SYS5 thing to do,
but as(1) on the unixpc will not assemble a file with a .ident  in it.

The following diff will make gcc-cpp, (at least from GCC-1.28),
treat #ident the same as #sccs, (ie. ignore both).
I do not think that this is the appropriate change to make in the
GCC distribution, as it will make all gcc compilers ignore #ident.
Any suggestions out there.
