Is there a way to know which version of gcc was used with a certain ruby
binary?
Thanks!

I'm curious: Why would someone want to know that?

I was looking for a way to include it in the output of the ruby
benchmark suite so that the logs were more descriptive of which version
of Ruby was being run :)

Currently I can glean this information from rbconfig:
Ruby VM: ruby [ruby 1.8.6 (2008-07-17 patchlevel 279) [i386-mingw32];-g
-O2]

The -O2 is quite useful [don't want to compare versions that are
compiled with different -O settings and call it fair].. The version of
GCC would also be useful for the same reason.

You only want the options passed to GCC? They're in rbconfig.rb

why not build the ruby yourself as part of the benchmark suite? then
"gcc --version" is valid.

Good idea.

re: which options I want. I have the info in rbconfig [parameters] but
I was wondering if ruby knew which version of the compiler was used for
itself somehow :)
