Attemping to compile anything under Windows 2000 (Release Canadate 2) crashes.
Compiling the first file works fine.
However during compilation of the second file, 'ntvwm' generates a fault and
brings up Dr. Watson.
The second file being compiled, never completes.

Example:
C:\Q1Src\WinQuake>make
 gcc -O2 -Wall -fomit-frame-pointer -fno-strength-reduce -funroll-loops   -c   r_light.c -o r_light.o
gcc -O2 -Wall -fomit-frame-pointer -fno-strength-reduce -funroll-loops   -c r_mi
sc.c -o r_misc.o

r_light.o is created, but r_misc.o isn't.

This is probably some bug in Windows 2000, which is still in beta.
Please report this to Microsoft.

Btw, other users reported success with Windows 2000.
