32 dnl AC_CHECK_CC_OPT(-fvomit-frame,vomitframe)
33 dnl would show a message as like
34 dnl "checking wether gcc accepts -fvomit-frame ... no"
35 dnl and sets the shell-variable $vomitframe to either "-fvomit-frame"
36 dnl or (in this case) just a simple "". In many cases you would then call
37 dnl AC_SUBST(_fvomit_frame_,$vomitframe) to create a substitution that
38 dnl could be fed as "CFLAGS = @_funsigned_char_@ @_fvomit_frame_@
39 dnl
40 dnl in consequence this function is much more general than their
41 dnl specific counterparts like ac_cxx_rtti.m4 that will test for
42 dnl -fno-rtti -fno-exceptions
