I was ignoring the warnings anyway.
I didn't look into that much but after upgrading to RHEL AS4, I am
able to compile successfully with --enable-thread-safety
Thanks,

The Intel compiler complains about global variables that are not marked
either static or extern. They are remarks so I think you are OK with
that.
The attached patch should remove the warnings but I am not applying it
because a non-static/extern global variable should be fine in C code.
The larger problem is that we are not picking up the proper thread flags
for the Intel C compiler. Any idea what they are? Please try compiling
in src/tools/thread manually to get the flags working and report back.
It isn't find the thread library functions like pthread_join.
