cygwin1.dll v1.3.11-3 crashing on Windows 2000

[Wu Yongwei]

Many programs, including gcc.exe and a simple hello.exe, crashed with the
new DLL in the Cygwin 1.3.11-3 upgrade. Restoring the old 1.3.10 DLL quieted
them.

The following the stack trace (with Dr MinGW) of a hello.exe compiled
with -g in 1.3.10 running in 1.3.11:

a.exe caused an Access Violation at location 61060962 in module cygwin1.dll
Reading from location 0000009c.

Registers:
eax=0000009c ebx=00000000 ecx=7ffde000 edx=610a43f0 esi=00018b00

Yes, it did not display the "Segmentation fault (core dumped)" message, but
wrote the .stackdump file and popped up an Access Violation dialogue box.

My OS is Chinese Windows 2000 SP2.
