sketch 4d692d801b Since revision 1.155 of bsd.prefs.mk, compiler.mk is required in package
Makefiles for testing CC_VERSION, not bsd.prefs.mk.  Reflect that change
in the provided example.

#
# This Makefile fragment implements handling for supported C/C++/Fortran
# compilers.
#
# The following variables are used by this file:
#
# PKGSRC_COMPILER
# A list of values specifying the chain of compilers to be used by
# pkgsrc to build packages.
#
# Valid values are:
# distcc distributed C/C++ (chainable)
# ccache compiler cache (chainable)
# gcc GNU
# mipspro Silicon Graphics, Inc. MIPSpro (n32/n64)
# mipspro-ucode Silicon Graphics, Inc. MIPSpro (o32)
# sunpro Sun Microsystems, Inc. WorkShip/Forte/Sun
# ONE Studio
#
# The default is "gcc". You can use ccache and/or distcc with an
# appropriate PKGSRC_COMPILER setting, e.g. "ccache distcc gcc".
# The chain should always end in a real compiler. This should only
# be set in /etc/mk.conf.
#
# GCC_REQD
# A list of version numbers used to determine the minimum
# version of GCC required by a package. This value should only
# be appended to by a package Makefile.
#
# NOTE: Be conservative when setting GCC_REQD, as lang/gcc3 is
# known not to build on some platforms, e.g. Darwin. If gcc3 is
# required, set GCC_REQD=3.0 so that we do not try to pull in
# lang/gcc3 unnecessarily and have it fail.
#
# USE_PKGSRC_GCC
# Force using the appropriate version of GCC from pkgsrc based on
# GCC_REQD instead of the native compiler.
#
# USE_GCC_SHLIB
# Indicates that a package uses GCC shared libraries, so we
# register a runtime dependency on the compiler package.
#
# USE_LANGUAGES
# Lists the languages used in the source code of the package,
# and is used to determine the correct compilers to install.
# Valid values are: c, c++, fortran, java, objc. The default
# is "c".
#
# The following variables are defined, and available for testing in
# package Makefiles:
#
# CC_VERSION
# The compiler and version being used, e.g.,
#
# .include "../../mk/compiler.mk"
#
# .if !empty(CC_VERSION:Mgcc-3*)
# ...
# .endif
#
# The following variables are deprecated:
#
# USE_GCC2, USE_GCC3, USE_SUNPRO, USE_MIPSPRO
.if !defined(BSD_COMPILER_MK)
BSD_COMPILER_MK= defined
.include "../../mk/bsd.prefs.mk"
# XXX Add this gross and completely inaccurate hack. Packages that
# XXX set USE_GCC_SHLIB should be adjusted to set USE_LANGUAGES
# XXX correctly (most likely by saying it needs either "c++" or
# XXX "c c++"). This is here for now so that ~85 packages won't
# XXX suddenly break.
#
.if defined(USE_GCC_SHLIB)
USE_LANGUAGES?= c c++
.endif
# By default, assume that the package requires a C compiler.
USE_LANGUAGES?= c
# Support some deprecated variables for a while. They'll be removed
# after the pkgsrc-2004Q1 branch is cut.
