I suggest the following changes to nt/configure.bat. The purpose is
to leave behind a useful config.log file which could be perused to
find out why various parts of the configure stage failed.
This was tested on Windows XP SP2, but my main concern is about older
Windows versions, like Windows 9x: the changes use advanced
redirection features that are unavailable with COMMAND.COM, the
default shell that comes with those older versions of Windows. OTOH,
the current version of configure.bat in CVS already uses features like
"2>junk.err", so I guess this causes some harmless error message?
I'll wait for Jason and others to comment on these changes, before I
decide whether to commit them. TIA
