broke gcc

cygwin.dll. I rebooted, searched my harddrive for cygwin1.dll (there's one copy from my original installation of cygwin), and reinstalled some packages, including gcc. Any ideas on how to troubleshoot or fix this? Thanks. Jim Holder __ Do you Yahoo!? Yahoo

finding out how much memory is available with malloc, gcc, cygwin

A program similar to the one listed below works for me on Linux but not under Cygwin. The idea is to find out how memory I can allocate on the machine. The Cygwin version keeps going (past 700MB), reporting that it has allocated more memory than the machine has. What am I doing wrong? Thanks.
