Thanks Dave, it's fixed. It looks like the problem was the cygwin1.dll
in C:\Windows\SYSTEM. I have no idea why that was there. (I am not the
first to use this machine.)
As a precaution I have also removed
C:\Users\XXXXXXXX\home\apps\gcc-4.7-20120128\bin from my PATH. I had
built it with --program-suffix=-4.7, but the following potentially
conflicting files remain there with their names untouched:
cyggfortran-3.dll
cygssp-0.dll
cygstdc++-6.dll
Thanks again.
