++# 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+.
