manual, as Info files. You can regenerate those with @w{@code{make
info}}, but it shouldn't be necessary.
The library has a number of special-purpose configuration parameters
which you can find in @file{Makeconfig}. These can be overwritten with
the file @file{configparms}. To change them, create a
@file{configparms} in your build directory and add values as appropriate
for your system. The file is included and parsed by @code{make} and has
to follow the conventions for makefiles.
It is easy to configure the GNU C library for cross-compilation by
setting a few variables in @file{configparms}. Set @code{CC} to the
cross-compiler for the target you configured the library for; it is
important to use this same @code{CC} value when running
@code{configure}, like this: @samp{CC=@var{target}-gcc configure
@var{target}}. Set @code{BUILD_CC} to the compiler to use for for
programs run on the build system as part of compiling the library. You
may need to set @code{AR} and @code{RANLIB} to cross-compiling versions
of @code{ar} and @code{ranlib} if the native tools are not configured to
work with object files for the target you configured for.

The GNU C library can only be compiled with the GNU C compiler family.
As of the 2.1 release, EGCS 1.0.3 or higher is required. GCC 2.8.1 can
also be used (but see the FAQ for reasons why you might not want to).
Earlier versions simply are too buggy. As of this writing, GCC 2.95.1
Earlier versions simply are too buggy. As of this writing, GCC 2.95.2
is the compiler we advise to use.
You can use whatever compiler you like to compile programs that use GNU
