No. It's using the old GCC, but it is not using the old linker,
because the environment variables that the external compiler driver
sets up: they shouldn't affect the internal compiler that libtool uses
to re-link the executable, but they do.
I think the right thing to do is to arrange for the libtool
wrapper/relinker script to set GCC_EXEC_PREFIX, COMPILER_PATH and
LIBRARY_PATH to the values they had when the wrapper script was
created, if the compiler in use is GCC.
Here's an (untested, because I have to leave right now) patch that
should fix this problem. I'll make sure a similar (at least in
spirit) patch gets into the libtool CVS tree. The final (i.e., for
libtool) version should probably only save these variables if GCC is
the compiler in use, but this is not strictly necessary, and it won't
hurt to put is in as-is in the Sourceware CVS repo (assuming it
works :-) Ok to install?
H.J., thank you so much for your patience and for helping us figure
out what was the real problem.
