This will slow down the compiler and may only work properly if you
are building the compiler with GNU C.
-The @file{configure} script searches subdirectories of the source
-directory for other compilers that are to be integrated into GNU CC.
-The GNU compiler for C++, called G++ is in a subdirectory named
-@file{cp}. @file{configure} inserts rules into @file{Makefile} to build
-all of those compilers.
-
-Here we spell out what files will be set up by @code{configure}. Normally
-you need not be concerned with these files.
-
-@itemize @bullet
-@item
-@ifset INTERNALS
-A file named @file{config.h} is created that contains a @samp{#include}
-of the top-level config file for the machine you will run the compiler
-on (@pxref{Config}). This file is responsible for defining information
-about the host machine. It includes @file{tm.h}.
-@end ifset
-@ifclear INTERNALS
-A file named @file{config.h} is created that contains a @samp{#include}
-of the top-level config file for the machine you will run the compiler
-on (@pxref{Config,,The Configuration File, gcc.info, Using and Porting
-GCC}). This file is responsible for defining information about the host
-machine. It includes @file{tm.h}.
-@end ifclear
-
-The top-level config file is located in the subdirectory @file{config}.
-Its name is always @file{xm-@var{something}.h}; usually
-@file{xm-@var{machine}.h}, but there are some exceptions.
-
-If your system does not support symbolic links, you might want to
-set up @file{config.h} to contain a @samp{#include} command which
-refers to the appropriate file.
-
-@item
-A file named @file{tconfig.h} is created which includes the top-level config
-file for your target machine. This is used for compiling certain
-programs to run on that machine.
-
-@item
-A file named @file{tm.h} is created which includes the
-machine-description macro file for your target machine. It should be in
-the subdirectory @file{config} and its name is often
-@file{@var{machine}.h}.
