un/dosifyPath in SysTools.lhs bug?

I always configure with
and everything is fine. I see that the Building Guide suggests=20
which I suspect is plain wrong. =20
Try with the path syntax I use, and see if that helps. Meanwhile I'll
modify the building guide.

| I'm trying to build ghc (the 5.04.3 source tarball) on Windows, but
| after the ghc-inplace is written and is used to build something, ghc
| If I cut and paste the command* and run it with -v, it's evident that

| ./configured --with-gcc.
| But ghc is a mingw executable! So I think runSomething in

| clear that it expects a 'native' program. Anyway, the problem can be
| by changing:
| cmd_line =3D pgm ++ ...
| cmd_line =3D (dosifyPath pgm) ++ ...
| And dosifyPath and undosifyPath (#if defined(mingw32_HOST_OS)) have no
| regard for drive letters! Shouldn't they be something like:
| unDosifyPath xs =3D
| case (subst '\\' '/' xs) of
| drive : ':' : rest -> "/cygdrive/" ++ (drive : rest)
| xs' -> xs'
| dosifyPath stuff
| =3D subst '/' '\\' real_stuff
| -- fully convince myself that /cygdrive/ prefixes cannot
| -- really appear here.
| cygdrive_prefix =3D "/cygdrive/"
| | cygdrive_prefix `isPrefixOf` stuff =3D
| case (dropList cygdrive_prefix stuff) of
| drive : rest -> drive : ':' : rest
| | otherwise =3D stuff
| That comment re: cygdrive in dosifyPath is rather ominous... but those
| changes at least allow ghc-inplace to start compiling the next
| The build then barfed in rts doing:
| ../../ghc/compiler/ghc-inplace -O2 -package-name rts -O -Rghc-timing
| Exception.hc -o Exception.o
| Because Exception.hc couldn't #include "Stg.h"; it seems the GHC
| path was specified as a couple of Options instead of a single
| which meant showOptions didn't dosify it.
| Doing a quick hack in showOptions to peek at Options for the
| prefix keeps the build going. What I'm wondering is:
| Is anyone building GHC on Windows, and if so, how do you do it?
