enable/disable threads when installing gcc

[Long Li]

Hi, Guys,

I have just installed GCC 3.0 on my redhat 7.2 Linux
machine. During the configuration of GCC, I found the
option --enable-threads was turned off, which means, I
guess, the GCC 3.0 on my machine does not support
thread. However, when I include the pthread.h file and
use the GCC 3.0 to compile, it worked and the result
showed me some threads switching cases. So what does
the --enable-threads option do? Does it really turn
off the thread or just a default case, and you can
overwrite it when compling?


Thanks a lot!


Long
