Insight on cygwin

[Steven Schram]

I am building Insight on cygwin.  I get errors from the lack of "psapi.h"
and "imagehlp.h" when compiling win32-nat.c.  Can you direct me as to the
source of these files?  Are they Microsoft redistributables?

I am using a direct binary install of Cygwin 1.0, with egcs-2.91.57.

Thanks,
Steven Schram
