#
# SYNOPSIS
# DESCRIPTION
#
# Defines CODE_COVERAGE_CPPFLAGS, CODE_COVERAGE_CFLAGS,
-# CODE_COVERAGE_CXXFLAGS and CODE_COVERAGE_LDFLAGS which should be
-# included in the CPPFLAGS, CFLAGS CXXFLAGS and LIBS/LDFLAGS variables of
-# every build target (program or library) which should be built with code
+# 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
# Test also for gcov program and create GCOV variable that could be
# substituted.
#
-# Note that all optimisation flags in CFLAGS must be disabled when code
+# Note that all optimization flags in CFLAGS must be disabled when code
# coverage is enabled.
#
# Usage example:
# Makefile.am:
#
# @CODE_COVERAGE_RULES@
-# my_program_LIBS = ... $(CODE_COVERAGE_LDFLAGS) ...
+# my_program_LIBS = ... $(CODE_COVERAGE_LIBS) ...
# my_program_CPPFLAGS = ... $(CODE_COVERAGE_CPPFLAGS) ...
# my_program_CFLAGS = ... $(CODE_COVERAGE_CFLAGS) ...
# my_program_CXXFLAGS = ... $(CODE_COVERAGE_CXXFLAGS) ...
# (`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.
+#

# under LGPLv2.1+.
