* Name: Barrett Richardson

* When: Thu Dec 15 10:31:11 EST 1994
*
* callable function:
*
* double __divdf3(double a1, double a2);
*
* Does software divide of a1 / a2.
*
* Based largely on __divsf3() in floatlib.c in the gcc
* distribution.
*
* Purpose: To be used in conjunction with the -msoft-float
* option of gcc. You should be able to tack it to the
* end of floatlib.c included in the gcc distribution,
* and delete the __divdf3() already there which just
* calls the single precision function (or may just
* use the floating point processor with some configurations).
*
* You may use this code for whatever your heart desires.

* 0 if the two mantissa's are equal.

@itemx --disable-nls
The @samp{--enable-nls} option enables Native Language Support (NLS),
which lets GCC output diagnostics in languages other than American
English. No translations are available yet, so the main users of this
option now are those translating GCC's diagnostics who want to test
their work. Once translations become available, Native Language Support
will become enabled by default. The @samp{--disable-nls} option
disables NLS.
@cindex @code{gettext}
@item --with-included-gettext
If NLS is enabled, the GCC build procedure normally attempts to use the
host's @code{gettext} libraries, and falls back on GCC's copy of the GNU
@code{gettext} library only if the host libraries do not suffice. The
@samp{--with-included-gettext} option causes the build procedure to
prefer its copy of GNU @code{gettext}.
@cindex @code{catgets}

If NLS is enabled, and if the host lacks @code{gettext} but has the
inferior @code{catgets} interface, the GCC build procedure normally
ignores @code{catgets} and instead uses GCC's copy of the GNU

build procedure to use the host's @code{catgets} in this situation.

@node Configuration Files
@section Files Created by @code{configure}
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}.
@item
The command file @file{configure} also constructs the file
@file{Makefile} by adding some text to the template file
@file{Makefile.in}. The additional text comes from files in the
@file{config} directory, named @file{t-@var{target}} and
@file{x-@var{host}}. If these files do not exist, it means nothing
needs to be added for a given target or host.

These environment variables control the way that GNU CC uses
localization information that allow GNU CC to work with different
national conventions. GNU CC inspects the locale categories
@code{LC_CTYPE} and @code{LC_MESSAGES} if it has been configured to do
so. These locale categories can be set to any value supported by your
installation. A typical value is @samp{en_UK} for English in the United
Kingdom.
The @code{LC_CTYPE} environment variable specifies character
classification. GNU CC uses it to determine the character boundaries in
a string; this is needed for some multibyte encodings that contain quote
and escape characters that would otherwise be interpreted as a string
end or escape.
The @code{LC_MESSAGES} environment variable specifies the language to
use in diagnostic messages.
If the @code{LC_ALL} environment variable is set, it overrides the value
of @code{LC_CTYPE} and @code{LC_MESSAGES}; otherwise, @code{LC_CTYPE}
and @code{LC_MESSAGES} default to the value of the @code{LANG}
environment variable. If none of these variables are set, GNU CC
defaults to traditional C English behavior.
