-Configuring gcc to use certain flags by default is a simple matter of
-editing the 
-<FileName>/usr/local/lib/gcc-lib/<Replaceable>platform</Replaceable>/<Replaceable>version</Replaceable>/specs</FileName>
-file.
-The format of this file pretty simple.  The file is broken into
-sections, each of which is three lines long.  The first line is
-"*<Replaceable>section_name</Replaceable>:" (e.g. "*asm:").
-The second line is a list of flags,
-and the third line is blank.
-</para>

-<Para>
-The easiest change to make is to append
-the desired default flags to the list in the appropriate section.  As
-an example, let's suppose that I have linux running on a '486 with gcc
-2.7.2 installed in the default location.  In the file
-/usr/local/lib/gcc-lib/i486-linux/2.7.2/specs, 13 lines down I find
-the following section:
-<ProgramListing>
-- ----------SECTION----------
-*cc1:
-
-
-- ----------SECTION----------
-</ProgramListing>
-As you can see, there aren't any default flags.  If I always wanted
-compiles of C code to use "-m486 -fomit-frame-pointer", I would
-change it to look like:
-<ProgramListing>
-- ----------SECTION----------
-*cc1:
-- -m486 -fomit-frame-pointer
-
-- ----------SECTION----------
-</ProgramListing>
-If I wanted to be able to generate 386 code for another, older linux
-box lying around, I'd have to make it look like this:
-<ProgramListing>
-- ----------SECTION----------
-*cc1:
-%{!m386:-m486} -fomit-frame-pointer
-
-- ----------SECTION----------
-</ProgramListing>
-This will always omit frame pointers, any will build 486-optimized
-code unless -m386 is specified on the command line.
-</para>
-
-<Para>
-You can actually do quite a lot of customization with the specs file.
-Always remember, however, that these changes are global, and affect
-all users of the system.
