-# SYNOPSIS
-#
-# AX_CODE_COVERAGE()
-#
-# DESCRIPTION
-#
-# Defines CODE_COVERAGE_CPPFLAGS, CODE_COVERAGE_CFLAGS,
-# CODE_COVERAGE_CXXFLAGS and CODE_COVERAGE_LIBS which should be included
-# in the CPPFLAGS, CFLAGS CXXFLAGS and LIBS/LIBADD variables of every
-# build target (program or library) which should be built with code
-# coverage support. Also defines CODE_COVERAGE_RULES which should be
-# substituted in your Makefile; and $enable_code_coverage which can be
-# used in subsequent configure output. CODE_COVERAGE_ENABLED is defined
-# and substituted, and corresponds to the value of the
-# --enable-code-coverage option, which defaults to being disabled.
-#
-# Test also for gcov program and create GCOV variable that could be
-# substituted.
-#
-# Note that all optimization flags in CFLAGS must be disabled when code
-# coverage is enabled.
-#
-# Usage example:
-#
-# configure.ac:
-#
-# AX_CODE_COVERAGE
-#
-# Makefile.am:
-#
-# @CODE_COVERAGE_RULES@
-# my_program_LIBS = ... $(CODE_COVERAGE_LIBS) ...
-# my_program_CPPFLAGS = ... $(CODE_COVERAGE_CPPFLAGS) ...
-# my_program_CFLAGS = ... $(CODE_COVERAGE_CFLAGS) ...
-# my_program_CXXFLAGS = ... $(CODE_COVERAGE_CXXFLAGS) ...
-#
-# This results in a "check-code-coverage" rule being added to any
-# Makefile.am which includes "@CODE_COVERAGE_RULES@" (assuming the module
-# has been configured with --enable-code-coverage). Running `make
-# check-code-coverage` in that directory will run the module's test suite
-# (`make check`) and build a code coverage report detailing the code which
-# was touched, then print the URI for the report.
-#
-# In earlier versions of this macro, CODE_COVERAGE_LDFLAGS was defined
-# instead of CODE_COVERAGE_LIBS. They are both still defined, but use of
-# CODE_COVERAGE_LIBS is preferred for clarity; CODE_COVERAGE_LDFLAGS is
-# deprecated. They have the same value.
-#
-# This code was derived from Makefile.decl in GLib, originally licenced
-# under LGPLv2.1+.
