That's a pretty poor expectation from the outset (it might be g++ 2.95 or something). You can't do *anything* without expecting stuff from the compiler. Pick some real goals and some realistic expectations, don't just handwave about vague notions of 'portability' to unnamed systems which are broken in unspecified ways. -- .''`. ** Debian GNU/Linux ** | Andrew Suffield : :' : http://www.debian.org/ | `. `' | `- -><- |
