In fact, this is not necessary anymore. Cf README: you just need to
run configure in ghdl, then make copy-sources, and finally
configure and build gcc.
Thanks Tristan. I haven't found make copy-sources being mentioned in
README - maybe this could be added? Anyway, the "new" style build method
is more comfortable...
Should I simply remove dist.sh ?
Yes please. Either that, or fix it. It IMO makes no sense to keep broken
scripts...
Another issue. I'm trying to compile ghdl with gcc/gnat 5.0.0. I succeed
getting ghdl1 compiled, but then compiling standard aborts with an
exception. It doesn't matter whether I use the llvm or gcc backend...
