------- Comment #5 from jakub at gcc dot gnu dot org 2009-12-21 00:23 ------- If so, then you are using too old glibc headers with -std=gnu99, without fixincludes and without -fgnu89-inline. Only headers of glibc later than mid-2007 are prepared for -std=gnu99 with GCC 4.3 without fixincludes and without -fgnu89-inline.
