-   The current release of the C library contains some header files that
-the compiler normally provides: `stddef.h', `stdarg.h', and several
-files with names of the form `va-MACHINE.h'.  The versions of these
-files that came with older releases of GCC do not work properly with
-the GNU C library.  The `stddef.h' file in release 2.2 and later of GCC
-is correct.  If you have release 2.2 or later of GCC, use its version
-of `stddef.h' instead of the C library's.  To do this, put the line

-in release 2.3 and later of GCC.  `configure' will automatically detect

-compatible with the C library, and use its own if not.
-
-   There is a potential problem with the `size_t' type and versions of
-GCC prior to release 2.4.  ANSI C requires that `size_t' always be an
-unsigned type.  For compatibility with existing systems' header files,
-GCC defines `size_t' in `stddef.h' to be whatever type the system's
-`sys/types.h' defines it to be.  Most Unix systems that define `size_t'

-
-   The GNU C library code which expects `size_t' to be unsigned is
-correct.  The definition of `size_t' as a signed type is incorrect.
-Versions 2.4 and later of GCC always define `size_t' as an unsigned
-type, and GCC's `fixincludes' script massages the system's
-`sys/types.h' so as not to conflict with this.

-   In the meantime, we work around this problem by telling GCC

+Recommended Tools to Install the GNU C Library
+----------------------------------------------
+
+   We recommend installing the following GNU tools before attempting to
+build the GNU C library:
+
+   * `make' 3.75
+
+     You need the latest version of GNU `make'.  Modifying the GNU C
+     Library to work with other `make' programs would be so hard that we
+     recommend you port GNU `make' instead.  *Really.* We recommend
+     version GNU `make' version 3.75 or later.
+
+   * GCC 2.7.2
+
+     On most platforms, the GNU C library can only be compiled with the
+     GNU C compiler.  We recommend GCC version 2.7.2 or later; earlier
+     versions may have problems.
+
+   * `binutils' 2.6
+
+     Using the GNU `binutils' (assembler, linker, and related tools) is
+     preferable when possible, and they are required to build an ELF
+     shared C library.  We recommend `binutils' version 2.6 or later;
+     earlier versions are known to have problems.
+
+Supported Configurations
+------------------------
+
+   The GNU C Library currently supports configurations that match the
+following patterns:
