Details:

The configure script, when run under MinGW/MSYS on Windows-XP, introduces a
hard disk "error". While trying to "check if rename manages hard links
correctly" a systray message pops up:

"conftest.exe - Corrupt file"

and on reboot a chkdsk is performed.
(The latter is nasty on 150 GB NTFS partitions with > 250,000 files on it.
Takes ages to complete).

I think there are no real disk errors introduced, it's just that configure's
rename/hard link test under MinGW/MSYS seems to confuse Windows' HD disk
driver so that it sets the "dirty" flag.
Tatsuro reported that he didn't see this anymore on Windows 7.

Nevertheless, as it is known that hard links don't exist on Windows, this
configure test had better be left out when ./configure detects it runs under
Windows or MinGW (is that at all possible?)
Or could a configure option "--enable-MinGW" or so be added to avoid this
test?

BTW I didn't hit this issue when building additional tools and dependencies
(which also invoke configure).
