I assume you guys haven't looked into gcj and libjava - if you have
please feel free to correct me (I'm only looking into this as a followup
from Chris's comment last month).
...
There's no alloca in the standard cygwin includes, in winsup.h there's
#define alloca __builtin_alloca.

this errror is occuring during the make bootstrap process. AFAIK only
the gcc headers are used (I'm using the cvs GCC 3 branch).

I've done some debug tracking and patched gcj to apparently work
correctly under cygwin. libjava just seems to have some header issues.

Would inserting  the __builtin_alloca define be a reasonable workaround?
(__CYGWIN__ protected of course).
