The check is thus made with the flags: "LDFLAGS +# EXTRA-FLAGS FLAG". This can for example be used to force the linker to +# issue an error when a bad flag is given. +# +# INPUT gives an alternative input source to AC_LINK_IFELSE. +# +# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this +# macro in sync with AX_CHECK_{PREPROC,COMPILE}_FLAG. +# +# LICENSE +# +# Copyright (c) 2008 Guido U.
