--- Comment #1 from Douglas Mencken <dougmencken at gmail dot com> 2011-03-04 20:05:27 UTC --- With the following patch commands: http://ftp.osuosl.org/pub/manulix/scripts/build-scripts/PATCHCMDS/patchcmds-gcc GCC v 4.6.0 builds fine (snapshot 20110226). For those of you, who hates to follow links, the related part: # '-follow' may be not supported by 'find' producing an error: "find: unrecognized: -follow"; # the following is aimed to fix that issue sed -i 's/-follow //g' ./libjava/classpath/lib/gen-classlist.sh.in sed -i 's/-follow //g' ./libjava/contrib/rebuild-gcj-db.in sed -i 's/-follow //g' ./libjava/classpath/tools/Makefile.in sed -i 's/-follow //g' ./libjava/classpath/tools/Makefile.am Really, '-follow' is not needed at all.
