So it is. Sorry!

I went through the same mistake the first time I built Emacs with MSYS, 
went to the instruction, got it right.

But now, after a few successful builds this way, and after switching 
from Windows to GNU/Linux and back a few times (I use systems of both 
kinds), on the one hand, I felt confident that I knew how to do it, on 
the other hand, the last few times I built Emacs were on Linux, so I 
completely forgot about "msysconfig.sh".

Like Glenn said, it would be great if ./configure aborted when the 
environment is MSYS (would it be too hard to detect that?), or delegated 
transparently to ./nt/msysconfig.sh.
