Subject: configure: rationalize Xlib tests + minor fixes
X-Git-Tag: 1.0.0-pre1~361
X-Git-Url: https://git.sesse.net/?a=commitdiff_plain;h=20092f079d3fedeb7e9050f1075656c1c63a4e4c;p=vlc

configure: rationalize Xlib tests + minor fixes

 * gather all tests (that I could find)
 * X_FLAGS -> X_CFLAGS
 * test for Xlib.h only once
 * cleanup defaults (especially XvMC was silly)
 * factorize CPPFLAGS

 dnl it seems that autoconf do the pkg-config detection only for the first PKG_CHECK_MODULES in the configure.ac ( which is logical) but in our case it is nested in a if so it was not working if you're not on linux or have disable hal.
