[Scott, W Alan]

Ditto for us.  4.1.2 is the oldest we seem to have.

I'd be interested to know from the community what are the oldest compilers you care about?  Anyone out there using a compiler older than 5 years or so?

 I'd say for gcc, 4.1.x is likely the oldest you'd need to bother with.  That's the system compiler for RHEL5 and SLES10, both of which are EOL'd but still actively deployed.  That being said, chances are pretty high that even on those systems, you'd have a newer compiler available via system packages.  RHEL5.5 and up has /usr/bin/gcc44 and SLES 10 has /usr/bin/gcc-4.3, both available as system packages and an alternative to the older /usr/bin/gcc used to compiler their respective kernels.
