The situation is just as follows:

Operating system: Fedora Core 1 GPC - release: binary, gpc-20030830-with-gcc.i686-pc-linux-gnu.tar.gz - probably not important, because there were similar messages with other versions. I've only tried binary, because i can't compile the source, there is a "command not found" message.
