Re: [PATCH 2/4] Add Visium support to libgcc
Well, you'll need FSF approval to relicense - and unless you want to keep the same sources used verbatim in both places, the GPL+exception notice is the obvious one given such approval. (But in any case, putting in LGPL files without a license exception seems a bad idea, because it goes against the standard message about building your program with GCC not imposing restrictions on distribution of the resulting binary.) OK, I'm going to reimplement it based on libgcc2.c then. -- Eric Botcazou
