When buildin gcc in a directory outside the gcc source tree, a fresh build is normally started with a 'make distclean'. After that command, build subdirectories remain (depending on how far one got in the process): $ ls -CF fixincludes/ gcc/ intl/ libcpp/ libdecnumber/ Does that affect the next configuration? It does for me if I change any environment variables. I think a bug report is in order. Comments? -Tom Thomas M. Browder, Jr. Niceville, Florida USA
