I cannot build emacs anymore.

Sorry to hear that, but I cannot reproduce any of the failures on my
machine, it still bootstraps and builds for me, both with and without
"--jobs".

I didn't specify jobs at all. I tried both cmd.com and cygwin's
bash. cmd.com yields:
C:\cvsemacs\emacs\nt>mingw32-make bootstrap
mkdir "oo-spd"
mkdir "oo-spd/i386"
echo oo-spd/i386 > stamp_BLD
gcc -I. -DWIN32_LEAN_AND_MEAN -D_WIN32_WINNT=0x0400 -D_X86_=1 -c -mno-cygwin -mtune=pentium4 -O2 -Di386 -D_CRTAPI1=_cdecl -o oo-spd/i386/addsection.o addsection.c process_begin: CreateProcess(NULL, gcc -I. -DWIN32_LEAN_AND_MEAN -D_WIN32_WINNT=0x0400 -D_X86_=1 -c -mno-cygwin -mtune=pentium4 -O2 -Di386 -D_CRTAPI1=_cdecl -o
oo-spd/i386/addsection.o addsection.c, ...) failed.
make (e=2): The system cannot find the file specified.
              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I feel terribly stupid, because I cannot figure out what is the file
it doesn't find here.  It cannot be the oo-spd/i386 directory since it
was just created before the compilation command.  And it cannot be
addsection.c, because you are in the nt/ subdirectory, where
addsection.c lives.  Could you please try to find out what file is
missing?

 From bash:
$ mingw32-make bootstrap

I think I can understand this one; sounds like some bug in the MinGW
make and/or in its interaction with the Cygwin Bash.  Note the lone
backslash above and the leading blank in ` temacs'.

I made some changes to work around this; please resync and try again.
(Needless to say, it still bootstraps for me, at least without --jobs.
Will try with --jobs shortly.)

I just performed a fresh checkout and managed to complete the entire build bootstrap process without problem (this one without specifying --jobs=2). The only thing different from last night was that I had upgraded TCI (an alternative to rxvt) to the latest beta but that shouldn't make a difference I think. I did this checkout before I saw the message I'm replying to now, don't know if I got the changes or not but it worked now. I will do a rebuild again and time it this time and then time another rebuild this time with --jobs=2 and see if both can complete successfully (and their respective times will be interesting for me to compare).
