/** Use gcc attribute to check printf fns. a1 is argument to format()
* in the above macro. This is needed to support Heimdal's printf
* decorations. Note that some gcc 2.x versions don't handle this
util/attr.h: use HAVE___ATTRIBUTE__, not __GNUC__ comparisons The comparisons that look like #if (__GNUC__ >= 3) && (__GNUC_MINOR__ >= 1 ) fail if __GNUC_MINOR__ is 0. The intended comparison is something more like #if __GNUC__ > 3 || (__GNUC__ == 3 && __GNUC_MINOR__ >= 1) However, given that: * these checks are really trying to test the presence of __attribute__, * there are now credible compilers that are not GCC, which have __attribute__ but might not be good at emulating __GNUC__ numbers, and * we really face little risk of running into GCC 2.95 * we have a HAVE___ATTRIBUTE__ check in ./configure let's not do the version comparisons. (Untested on GCC 2.95, GCC 3.0 and GCC 3.1).
