# compute directories for invoking GCC
#
# The gcc toolset can be user-configured using the following
# variables:
#
# GCC_ROOT_DIRECTORY
#       The directory in which GCC was installed. Defaults to
#       unset. Usually, there is no need to set this variable at
#       all. However, if G++ is not in the path it is usually
#       sufficient to configure this one variable. More fine-grained
#       configuration is available by setting the following:
#
# GCC_BIN_DIRECTORY
#       the directory prefix used to find the gcc executables. Defaults to
#       $(GCC_ROOT_DIRECTORY)/bin/, or "" if GCC_ROOT_DIRECTORY is
#       not set.
#
# GCC_INCLUDE_DIRECTORY
#       the directory in which to find system includes. Defaults to
#       empty.
#
# GCC_STDLIB_DIRECTORY
#       the directory in which to find the standard library
#       objects associated with this build of gcc. Defaults to
#       $(GCC_ROOT_DIRECTORY)/lib. 
#
# GXX
#       The name by which g++ is invoked. You can also use this in
#       lieu of setting the <cxxflags> property to force options such
#       as "-V3.0.4" into the g++ command line: "-sGXX=g++ -V3.0.4".
#
# GCC
#       Similar to GXX, the name by which gcc is invoked for "C"
#       language targets.
