# Some notes, Fri May 16 12:31:32 PDT 2003:
#
# Why i486 and not i386? Because the shared C++ libraries in gcc-3.2.x will
# require 486 opcodes even when a 386 target is used (so we already weren't
# compatible with the i386 for Slackware 9.0, didn't notice, and nobody
# complained :-). gcc-3.3 fixes this issue and allows you to build a 386
# compiler, but the fix is done in a way that produces binaries that are not
# compatible with gcc-3.2.x compiled binaries. To retain compatibility with
# Slackware 9.0, we'll have to use i486 (or better) as the compiler target
# for gcc-3.3.
#
# It's time to say goodbye to i386 support in Slackware. I've surveyed 386
# usage online, and the most common thing I see people say when someone asks
# about running Linux on a 386 is to "run Slackware", but then they also
# usually go on to say "be sure to get an OLD version, like 4.0, before glibc,
# because it'll be more efficient." Now, if that's the general advice, then
# I see no reason to continue 386 support in the latest Slackware (and indeed
# it's no longer easily possible).

# Note by Eric Hameleers, Sun Mar 25 22:01:09 UTC 2007
# -----------------------------------------------------------------------------
# This is a gcc34 compatibility SlackBuild for use in Slackware > 11.0 ,
# where gcc4 is the default compiler suite.
# This gcc34 build installs to /usr/gcc34 and will not interfere with gcc4.
# *** Use gcc34 in your scripts, as follows ***
# * By using environment variables:
# Most softwares support the CC and CXX environment variables.
# First assign them, then run configure and/or make. Example:
# CC=gcc34 CXX=g++34 ./configure
#
# * Using configure support:
# If the software is using the standard GNU automake and configure,
# then there is a chance it supports other compilers by passing in
# a setting to the configure script.
# First run configure --help to see if it mentions anything.
# The following example is from MPlayer:
# ./configure --help
# ./configure --cc=gcc34
