# in the common scenario, target-specific tests are preceded
3ae283
# by a single invocation of cfgtest_target_section, whereas
3ae283
# native (build) system tests are preceded by the invocation
3ae283
# of cfgtest_native_section.

3ae283
# mb_cfgtest_cc:      the compiler used for the current test
3ae283
# mb_cfgtest_cflags:  the compiler flags used for the current test
3ae283
# mb_cfgtest_cfgtype: the type of the current test (target/native)
3ae283
# mb_cfgtest_makevar: the make variable affected by the current test
3ae283
# mb_cfgtest_headers: headers for ad-hoc inclusion with the current test
