gcc -c -g -I- -I. -Iada -I/cvs/gcc-svn/trunk/gcc/ada /cvs/gcc-svn/trunk/gcc/ada/ada.ads -o ada/ada.oada.ads:16:01: language defined units may not be recompiledHere you are missing "-gnatpg gnata" in your line, although that could be "-gnatg" or "-gnatpgn"
So you need a -gnat<something> option, or compilation fails?
