Don't libraries need their own build system anyway if they are to be portable?
I imagined putting the standard libraries in a single source repository. By the "standard libraries", I mean loosely speaking those libraries which are going to be distributed with most compilers (i.e. like the current hslibs setup). The libraries could have a standalone build system, but at least for GHC this would mean duplicating most of the fptools build system in the libraries tree (because we need to support ways, GHCi .o files, DLLs, split object files etc. etc.), but NHC and Hugs require a much more minimal build system.
Technically, I think, it might be cleaner to have build system for the libraries that works with all compilers, rather than different build systems for different compilers. Cheers, Manuel
