By the way, the GCC we used are 2.96 and 3.2.2.

Subject: Re: vl2mv issue
Dhammika:
We tried compiling vl2mv on both RedHat Linux 7.1 and 9.0 (we don't have a
8.0 machine), and didn't see any problem. There are a few warnings during
make, but they are different from what your mention.
Could you please (1) send us a list of the warnings produced by make, and
(2) try on a 9.0 machine if possible ?
Thanks,
Chao
