Some comments:
A look at the licenses: libgm2/p2c/*: GPL 3+ libgm2/libiso/*: LGPL 2.1+ libgm2/libmin/libc.c: GPL 3+ libgm2/liblog/*: LGPL 2.1+ libgm2/libpim/*: LGPL 2.1+ libgm2/libpim/Selective.c: GPL 3+ libgm2/libpim/wrapc.c: GPL 3+ libgm2/libpth/*: LGPL 2.1+ gcc/gm2/ulm-lib-gm2/* GPL 3+, Ulm copyright holder? gcc/gm2/gm2-libs/*.def GPL 3+ gcc/gm2/gm2-libs/Break.def LGPL 2.1+ gcc/gm2/gm2-libs/*.mod LGPL 2.1+ gcc/gm2/gm2-libs/Builtins.mod GPL 3+ I didn't look at everything in gcc/gm2, however it's not clear for me when a file is LGPL or GPL. And at least in gm2-libs, it seems to be mixed randomly. First I thought all definition modules were GPL, and implementation modules were LGPL, but that's not the case. So currently all code linked with the runtime libs becomes GPL 3+? For the ulm lib, the files mention the Ulm university as the copyright holder, but it's not clear which license these files had before they were imported. libgm2 seems to be mostly LGPL except for two files. Intended? Matthias
