I've been adding cygwin support to http://kegel.com/crosstool so I can build hetrogenous distcc clusters targeting e.g. Red Hat 6.2. I have a nice automated shell script to do this; works great under Linux, and I'm slowly chipping away at the problems under Cygwin. The latest one is a Heisenbug: a submake crashes, but only if I don't run it under gdb :-(
Aha. Using 'make -d' shows more detail:

Got a SIGCHLD; 1 unreaped children.
Reaping losing child 0x0a07a738 PID 492
make[1]: *** [iconvdata/lib] Segmentation fault (core dumped)
Removing child 0x0a07a738 PID 492 from chain.
so the recursion in extra-module.mk (which is expected, though I don't know how many repeats are normal) is going awry somehow.
I'll look into it more when I don't have a sqiggly baby on my lap who wants to help. - Dan
