[Angelo Graziosi]

Iwant to flag this for the sake of completeness.


After amost a month of succeful daily build of Emacs-CVS (with GCC-4.0.3
very stable) the build fail in this way:

This kind of error, periodically, comes out under Cygwin.



Its structure is alway the same:

Fatal error (6)/bin/sh: line <...>:  <...> Aborted (core dumped)
