Yes, I think you can set UNSUPPORTED_COMPILER.pcc in the Makefile and it
will proceed using a different one
For the time being, I'll make a note of all the tools that pcc cannot
currently build, and set Makefiles accordingly. I'm not sure if these
tools under gpl track upstream or not, so at least for tonight I'm not
sure if feel comfortable changing the actual source code of binutils
to make pcc compile it successfully. Although perhaps submitting a
patch to binutils that undefines __restrict in arrays if pcc is being
used is a possible solution for the time being.
