You could achieve this by tedious process of individually building the runtime libraries prior to building the compiler. I don't think it is worth the extra work and would rather let users of older computers compile their own or use older distributions from the period age of the users computer. However, there is always the ignorant who seem to want to use cutting edge software on over-the-hill computers and bite themselves in the process derriere. -- Earnie -- https://sites.google.com/site/earnieboyd ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
