gcc version 4.2.2
Most options are easy to find, except for --without-x. So, what is this option for?
The summary of gcc options didn't help, since the option is not listed.
해결책
Configure options are not options to gcc. They are given when gcc is built to the configure script. To find out what they mean, check the gcc source documentation.
If --with-x is not there, it doesn't have to mean anything, as autoconf-generated configure scripts can ignore flags.
However, it is listed on http://gcc.gnu.org/install/configure.html -
--with-x
Use the X Window System.
