MSYS build - stage 2 problem

Here is the result with latest 6.2.1 binary and yesterday's CVS code.

Earleir I reported that I get the same error with hsc2hs and I did a slight
change in hsc2hs' Main.hs, namely:

l.812:

#if defined(mingw32_HOST_OS)
subst a b ls = map (\ x -> if x == a then b else x) ls
unDosifyPath xs = subst '\\' '/' xs
-- fix for msys build
-- dosifyPath xs = subst '/' '\\' xs
dosifyPath xs = xs

In that way, when hsc2hs is invoked I get:

------------------------------------------------------------------------
../../ghc/utils/hsc2hs/hsc2hs-inplace -Iinclude -I../../ghc/includes -Icbits/regex -I.    System/CPUTime.hsc

Fail: System/CPUTime_hsc_make.o: removeFile: does not exist (No such file or directory)

As you can see, now there is correct parameter, i.e. System/CPUTime.hsc


However, closer look at the process (after manually creating 
CPUTime_hsc_make.c) reveals the problem:

unknown at GAURA-GOUR /ghc/fptools/libraries/base
$ ../../ghc/utils/hsc2hs/hsc2hs -v -Iinclude -I../../ghc/includes -Icbits/regex

Similar thing when invoking next *.hsc:

unknown at GAURA-GOUR /ghc/fptools/libraries/base
$ c:/MinGW/bin/gcc -c -mno-cygwin -D__GLASGOW_HASKELL__=602 -Ic:/ghc/fptools/gh

In file included from Signals.hsc:90:
c:/ghc/fptools/ghc/includes/Signals.h:19: error: parse error before "StgStablePtr"
Signals.hsc: In function `main':
Signals.hsc:125: error: `stdout' undeclared (first use in this function)
Signals.hsc:125: error: (Each undeclared identifier is reported only once
Signals.hsc:125: error: for each function it appears in.)

What is this?

Is it a step forward or backward?

Sincerely,
Gour
