I had to dump gcc44 specs file (-dumpspecs), then find a line that defines pthread option expansion and add shared clause the same as !shared clause there. And then I modified make.conf to use the new specs file for gcc44: CFLAGS+= -specs=/home/avg/devel/gcc/gcc44.specs This is a problem that upstream GCC has incorrect specs for -pthread option. To better see what I mean do: $ gcc -dumpspecs | fgrep -w pthread and $ gcc44 -dumpspecs | fgrep -w pthread -- Andriy Gapon
