Hi,
it has been reported that there are issues in trying to build Maxima on Cygwin
using ECL. Does this look like an ECL issue. See error message at

http://trac.sagemath.org/sage_trac/ticket/11260

I can confirm that this is _not_ specific to Windows XP. On a different virtualbox image I am getting the same errors. It seems that the problem is related to the use of fork() in cygwin, which is very fragile.

I am considering various possibilities. The obvious one is to reuse the code in RUN-PROGRAM that we already have for Windows/Mingw+MSVC in the Cygwin builds. I am not sure how easy this is -- still investigating.
