hi Frank As you know and I Just found out moving the tree from /usr/lib to /usr/local/lib doesn't work too well so I recompiled: make dist clean make clean (just in case ) ./configure --prefix=/usr/local then make LANGUAGES=pascal CFLAGS="-O2" until it crashed, then make LANGUAGES=pascal until it crashed, then created 2 directories and a soft link, ar->/usr/bin, then make LANGUAGES=pascal make pascal.install All this gave me a partially optimized gpc installed under /usr/local and working nicely thanks Russ
