Nmap Development: Re: gcc-4 troubleshooting

[Greg Darke <starstuff () optusnet com au>]

I found that the code will compile correctly with GCC 4, if you enable
the no-strict-aliasing option (because strict-aliasing is enabled with
level 2 or higher optimization).

The command I used to configure Nmap was:
./configure CFLAGS="-O2 -fno-strict-aliasing"

Is there a way that we can check for GCC 4 and then automatically use
the -fno-strict-aliasing option?
