Libraries that can have user specificed base paths are wrapped with GIT_STASH_FLAGS/GIT_UNSTASH_FLAGS to ensure that the proper versions on the system are tested. This ensures, for example, that the zlib tests for deflateUnbound are done with the version of zlib requested by the user. This is most useful in the absence of good settings for CPPFLAGS and/or LDFLAGS. Signed-off-by: Ben Walton <bwalton@artsci.utoronto.ca> Signed-off-by: Junio C Hamano <gitster@pobox.com>
