* Update the attributes.m4 macro file from xine-lib/lscube.Diego E. 'Flameeyes' Pettenò2008-11-191-0/+53
| | | | | Also use the new CC_CHECK_CFLAGS_APPEND macro instead of doing the for loop manually.
* Split out the lynx documentation generation autoconf code to an m4 macro.Diego 'Flameeyes' Pettenò2008-08-071-0/+24
| | | | | As many 0pointer projects use the same code, move it out on its own macro, and use that. The macro can then be shared across projects.
* Replace the CFLAGS-checking code with a common macro from xine-lib.Diego 'Flameeyes' Pettenò2008-08-071-0/+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.
* Create the m4 directory to host M4 macro files.Diego 'Flameeyes' Pettenò2008-08-071-0/+5
Make it known to autoconf and aclocal, add ignore file for libtool 2.2 macro files.
