Don’t use AC_EGREP_CPP if affected by CFLAGS * m4/float_h.m4 (gl_FLOAT_H): * m4/host-cpu-c-abi.m4 (gl_HOST_CPU_C_ABI): * m4/lib-ld.m4 (AC_LIB_PROG_LD): * m4/lib-prefix.m4 (AC_LIB_PREPARE_MULTILIB): * m4/year2038.m4 (gl_YEAR2038): Prefer AC_COMPILE_IFELSE to AC_EGREP_CPP when testing conditions likely to be affected by the choice of CFLAGS, since CFLAGS are not used by AC_EGREP_CPP. Without this patch, ‘./configure CFLAGS="-m32"’ fails on gzip with GNU/Linux x86-64.
