I solved my own problem... I never did figure out what was causing it, but I completely reinstalled cygwin from the beginning (rather than `upgrading' my win2k installation).
It now works like a champ. ============================================================= I have recently installed cygwin under windows XP and have been unable to use the g77 compiler. I get an error like ``g77 816 proc_subproc: Couldn't duplicate my handle<0x7E0> for PID 288, Win32 error 6.'' I get this same result with or without make. With make, I also get a pop-up box entitled ``16 bit MS-DOS Subsystem'' with the message ``Cygwin The NTVDM CPU has encountered an illegal instruction. CS:062b IP:017f OP63 74 20 44 4f...'' It's not at all obvious to me why NTVDM is being started by cygwin. I had previously been running g77 under cygwin with windows 2000 with no problems. I saved all my customized configuration files for the XP installation, but all the binaries are the latest.
