For instance it would be nice to clarify whether it's necessary to maintain two entirely separate sets of lib*.a for linking with the two styles of build. As I understand it there should be on the cygwin hand

*crt*.o for cygwin, libcygwin.a, (?)

and on the other

*crt*.o for mingw32, libcrtdll.a/libmsvcrt*.a, (?)

It seems, borne out by experience, that lib*.a for Windows DLLs should be interchangeable - since they're only calling the DLL entry points - but any lib that contains statically linkable code calling cygwin-only entry points or dependent on cygwin semantics through conditional compilation obviously won't be.

I wonder which those might be - libgcc.a presumably? Do/should such libs all reside in the appropriate gcc target/version directory?
