issue with file prcpucfg.h while building nspr on Windows

Hello,

I try to build nspr (nspr-4.6.7.tar.gz) on Windows XP SP2 with VC2005
express using Cygwin. The command-line I use is:

set path=C:\tools\cygwin\bin
call "C:\Program Files\Microsoft Platform SDK\SetEnv.Cmd" /XP32 /DEBUG
call "C:\Program Files\Microsoft Visual Studio 8\VC\vcvarsall.bat" x86
sh configure --enable-debug-rtl
cd pr/src
make clean all

Everything works fine until the compiler rise an error saying that
prcpucfg.h is not found in prtypes.h

The only place I found prcpucfg.h is in nsprpub\pr\src\md\mac (only
for mac I suppose)

If I use an "old" version of the file prcpucfg.h (for win32) I found
in another nspr package, and I put it in nsprpub\pr\include,
everything goes right.

Do I miss something about the file prcpucfg.h ?

Thanks for any help.

Franck.
