Subject: Prefer the standard CHECK_INCLUDE_FILE() and CHECK_INCLUDE_FILES(),
X-Git-Tag: v2.8.0~436
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=72f559e73d84c0f1e336af3cb61583e4c93db94e;p=thirdparty%2Flibarchive.git

Prefer the standard CHECK_INCLUDE_FILE() and CHECK_INCLUDE_FILES(),
refactor some of the header checks that rely on other headers.
