#
# This is the compiler definition for the GNU Compiler Collection.
#
# User-settable variables:
#
# GCCBASE
#	If using a native GCC and the compiler is not in $PATH then
#	this should be set to the base installation directory.
#
# USE_NATIVE_GCC
#	When set to "yes", the native gcc is used, no matter which
#	compiler version a package requires.
#
# USE_PKGSRC_GCC
#	When set to "yes", use an appropriate version of GCC from
#	pkgsrc based on GCC_REQD instead of the native compiler.
#
# USE_PKGSRC_GCC_RUNTIME
#	When set to "yes", the runtime gcc libraries (libgcc, libstdc++
#	etc) will be used from pkgsrc rather than the native compiler.
#
# GCC_VERSION_SUFFIX
#	Optional suffix for GCC binaries, i.e. if the installed names are like
#	/usr/bin/g++-5, /usr/bin/gcc-5 etc.

# Package-settable variables:
#
# GCC_REQD
#	The minimum version of the GNU Compiler Collection that is
#	required to build this package. Setting this variable doesn't
#	change the compiler that is used for building packages. See
#	ONLY_FOR_COMPILER for that purpose. This is a list of version
#	numbers, of which the maximum version is the definitive one.
#
#	This variable can also be set by the user when USE_PKGSRC_GCC
#	is in effect to ensure that a specific compiler is used for
#	packages which do not specify a higher version.
#
# USE_GCC_RUNTIME
#	Packages which build shared libraries but do not use libtool to
#	do so should define this variable.  It is used to determine whether
#	the gcc runtime should be depended upon when a user has enabled
#	USE_PKGSRC_GCC_RUNTIME.
#
# System-defined variables:
#
# CC_VERSION
#	A string of the form "gcc-4.3.2"
#
# CC_VERSION_STRING
#	The same(?) as CC_VERSION. FIXME: What's the difference between
#	the two?
#
# Keywords: gcc
