bww Bitwise works has released a port of GCC 9.2 compiler to OS/2 Warp, ArcaOS and eComStation. This is a new milestone for OS/2 software development that allows the community to port more open source software to this platform. The project port is available at github.
I am constantly impressed by the OS/2 community. Reading the github page, I was also impressed to learn that YUM+RPM got ported: http://trac.netlabs.org/rpm/wiki
