Which platform are you running on, and are you generating for X86 or X64?
[P.S.] I edited the command line after reading Lorri's observation below.
This is for x86_64.
$cat /proc/version Linux version 3.10.0-327.36.3.el7.x86_64 (firstname.lastname@example.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-4) (GCC) ) #1 SMP Mon Oct 24 16:09:20 UTC 2016
And when you do submit the problem report, please include the exact command line you used. I just experimented using the simple command line that mecej4 used, and was able to compile connolly.f. (Although, I admit, I compiled sizes.f first then the rest of the files)
