Subject:	compile with -fomit-frame-pointer and gcc

I have the following to report, perhaps it is a bug in gcc for Cygwin.

I wrote a C subroutine that allocated 60000 integers on the stack each time it 
was called. Under Cygwin gcc 2.95x this worked fine. However, when compiled with 
the current gcc 3.2 it fails  if compiled  using the -fomit-frame-pointer 
optimization (default from configure).

Without this optimization turned on all is well. Declaring the array static 
cleared up this problem and the program can  be compiled and run sucessfully 
using -fomit-frame-pointer.

Cheers,
Charles Werner
