Hello,
        Attached is a patch of some changes I made to the gcc wrapper to
get it to compile XFree CVS.

Basically it supports the use of '-' on the command line to read stdin
for gcc, as well as setting the file type back to none before adding the
last too .o files if the file type was set on the command line.

It is applied against uClibc-0.9.20
