* Replace the CFLAGS-checking code with a common macro from xine-lib.Diego 'Flameeyes' Pettenò2008-08-081-0/+258
Instead of writing custom code to check for cflags checking, import a copy of attributes.m4 from xine-lib's repository and use the CC_CHECK_CFLAGS macro. The advantage lies not only in being able to reduce the custom code in configure.ac, but also in the fact that the CC_CHECK_CFLAGS macro caches the results, making ./configure -C quite faster on second run. Check for the CFLAGS for any compiler and not just GCC, if the compiler does support the flag it is better to u se it anyway, otherwise it will be skipped.
