Failure to build HEAD include Time library on Windows

[Mitchell, Neil]

Hi,

(I have already reported this issue to libraries@, when it happened
using a binary dist and a hackage version, but this issue now occurs
while building GHC)

I added libraries/time to my GHC build, by commenting out the word
"extralibs" from ghc/packages, and I get the compile error:

c:/ghc-build/ghc/ghc/stage1-inplace/ghc.exe -Iinclude -package Win32-2.1
-packag
e base-4.0 -package old-locale-1.0 -optc-O2 -odir dist/build -c
cbits/HsTime.c -
o dist/build/cbits/HsTime.o

In file included from cbits\HsTime.c:1:0:

include\HsTime.h:4:26:  HsTimeConfig.h: No such file or directory

In file included from cbits\HsTime.c:1:0:

make[1]: *** [make.library.time] Error 2
make[1]: Leaving directory `/cygdrive/c/ghc-build/ghc/libraries'
make: *** [stage1] Error 2

I'm guessing the first error message is because configure didn't get
run, which could perhaps be a Cabal issue? The errors after that are
probably related - but if the configure file was generated I'd have a
chance at tracking them down myself.

Thanks

Neil
