-# This function handles the basics of setting the SRC_URI for a gcc ebuild.
-# To use, set SRC_URI with:
-#
-# SRC_URI="$(get_gcc_src_uri)"
-#
-# Other than the variables normally set by portage, this function's behavior
-# can be altered by setting the following:
-#
-# SNAPSHOT
-# If set, this variable signals that we should be using a snapshot of
-# gcc. It is expected to be in the format "YYYY-MM-DD". Note that if
-# the ebuild has a _pre suffix, this variable is ignored and the
-# prerelease tarball is used instead.
-#
-# BRANCH_UPDATE
-# If set, this variable signals that we should be using the main
-# release tarball (determined by ebuild version) and applying a
-# CVS branch update patch against it. The location of this branch
-# update patch is assumed to be in ${GENTOO_TOOLCHAIN_BASE_URI}.
-# Just like with SNAPSHOT, this variable is ignored if the ebuild
-# has a _pre suffix.
-#
-# PATCH_VER
-# PATCH_GCC_VER
-# This should be set to the version of the gentoo patch tarball.
-# The resulting filename of this tarball will be:
-# gcc-${PATCH_GCC_VER:-${GCC_RELEASE_VER}}-patches-${PATCH_VER}.tar.bz2
-#
-# PIE_VER
-# PIE_GCC_VER
-# These variables control patching in various updates for the logic
-# controlling Position Independant Executables. PIE_VER is expected
-# to be the version of this patch, and PIE_GCC_VER the gcc version of
-# the patch:
-# An example:
-# PIE_VER="8.7.6.5"
-# PIE_GCC_VER="3.4.0"
-# The resulting filename of this tarball will be:
-# gcc-${PIE_GCC_VER:-${GCC_RELEASE_VER}}-piepatches-v${PIE_VER}.tar.bz2
-#
-# SPECS_VER
-# SPECS_GCC_VER
-# This is for the minispecs files included in the hardened gcc-4.x
-# The specs files for hardenedno*, vanilla and for building the "specs" file.
-# SPECS_VER is expected to be the version of this patch, SPECS_GCC_VER
-# the gcc version of the patch.
-# An example:
-# SPECS_VER="8.7.6.5"
-# SPECS_GCC_VER="3.4.0"
-# The resulting filename of this tarball will be:
-# gcc-${SPECS_GCC_VER:-${GCC_RELEASE_VER}}-specs-${SPECS_VER}.tar.bz2
-#
-# HTB_VER
-# HTB_GCC_VER
-# These variables control whether or not an ebuild supports Herman
-# ten Brugge's bounds-checking patches. If you want to use a patch
-# for an older gcc version with a new gcc, make sure you set
-# HTB_GCC_VER to that version of gcc.
