The only case in which -B is needed at all is for an in-tree build.
That is, gcc and winsup are in the same source tree, so CC is set to
something like ./gcc/xgcc.
In that case, the -B is necessary so that gcc knows where to find the
cc1 binary.
If gcc and winsup are built from separate source trees, it isn't an issue.

Thanks,

Peter
