minor windoze build bug

[Martins Krikis]

Dear GNU,

Happened to stumble on this one; reporting to leave a record of how
one can get around it:

Was doing a windoze build of 21.4a, using nmake, VC and a bit of
cygwin. MS build tools were on C-drive but Emacs sources (and Cygwin,
if it matters) on D-drive. temacs.exe got built OK, but couldn't open
"the doc string file":

Finding pointers to doc strings...
Opening doc string file: no such file or directory, ../etc/DOC-X
NMAKE : fatal error U1077:
'"D:\Martins\emacs-21.4.old\src/obj-spd/i386/temacs.exe"' : return
code '0xffffffff'
Stop.

Quick fix for this problem: move Emacs sources somewhere on C-drive, build
there. Afterwards everything can be moved back to D-drive and the install
step can be done from there.

Thanks,

  Martins Krikis
