[Bug target/26385] New: 4.1 RC1 build failure on nm -P command (darwin7)

[fang at csl dot cornell dot edu]

gcc-4.1 RC1 (20060219) fails to create libstdc++-symbol.explist on
powerpc-apple-darwin7 with the following error message:

On darwin7, nm doesn't have a -P flag, whereas on darwin8, -P "writes
information in a portable output format."  (man page)  I couldn't find an
appropriate flag to substitute, would no flag be correct?

To get this far, I've followed the instructions found here:
http://opendarwin.org/projects/odcctools/usingodcctools.html
I'm using the 20060123 snapshot of odcctools.  

I've manually pathched "gcc/config/darwin.h" with:
perl -pi -e
's,/usr/bin/libtool,/Volumes/Local/fang/lib/odcctools/bin/libtool,;'
gcc/config/darwin.h
and configured with:
../configure --prefix=/Volumes/Local/fang \
        --program-suffix=-4.1 \
        --enable-languages=c,c++ \
        --disable-nls \
        --with-gmp=/sw \
        --with-mpfr=/sw \
        --infodir='${prefix}/share/info' \
        --with-included-gettext \
        --host=powerpc-apple-darwin`uname -r|cut -f1 -d.` \
        --with-as=/Volumes/Local/fang/lib/odcctools/bin/as \
        --with-ld=/Volumes/Local/fang/lib/odcctools/bin/ld

Is this something fixable in the source, detectable at configure time, or do we
need a target-specific patch?  (I can provide more configuration information if
needed for this report.)
