Does libglib.a (version 1.2.3) shipped with redhat linux2.2.5-23 has threads enabled?

Hi,

We need to use the threads enabled glib functions, but we don't know if the version 1.2.3 shipped with
linux 2.2.5-23 has that feature enabled. Does any one know how to find out? Is there any way to check
 it without writing a test code?

I compiled glib 1.2.3 with the following commands:

configure --enable-threads --with-threads=posix

Just want to know if those options were used when libglib.a was originally compiled by red hat.

Thanks a lot,
 Dan
