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