Re: how to detect gcc version in configure.ac

[David A. Wheeler]

This does not help you right now, but Dale Visser posted a patch to autoconf a 
few months ago that would solve your problem correctly. His patch adds the 
ability to check if a compiler supports a particular flag. My hope is that this 
ability will soon be added to autoconf. Clearly some people want it.
