--- Comment #2 from Dennis Clarke <dclarke at blastwave dot org> --- (In reply to Sam James from comment #1) > There's a bunch of porting required to get GNAT working on musl. I may work > on it this stage1. This was one of my primary concerns. I know that MUSL is a whole other world away from GlibC. So perhaps this is not really a bug with GCC but merely a porting issue. I have a bootstrap running now wherein I removed "ada" from the language options. Lets see what we get for testsuite results... however ... I can not fix the ada issue off the top of my head. May be trivial to fix given that the error only ever happens in the final stage of the bootstrap.
