Just adding my experience:
I tried to build a mingw arm-rtems4.11 compiler on cygwin using source
builder. I was not able to get it to work until I created a brand new
Windows 7 virtual machine and just installed cygwin.
Whatever combination of software I have on my main Windows 7 laptop kept
the build from completing.
Right now, I'm happy to use the Chris's mingw compiler that he cross
compiled on FreeBSD.
