+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:
+
+ alpha-dec-osf1

+ * The `libio' library used to implement `stdio' functions on some

+
+@comment string.h
+@comment POSIX
+@deftypefun {char *} strtok_r (char *@var{newstring}, const char *@var{delimiters}, char **@var{save_ptr})
+Just like @code{strtok} this function splits the string into several
+tokens which can be accessed be successive calls to @code{strtok_r}.
+The difference is that the information about the next token is not set
+up in some internal state information. Instead the caller has to
+provide another argument @var{save_ptr} which is a pointer to a string
+pointer. Calling @code{strtok_r} with a null pointer for
+@var{newstring} and leaving @var{save_ptr} between the calls unchanged
+does the job without limiting reentrancy.
+
+This function was proposed for POSIX.1b and can be found on many systems
+which support multi-threading.
+@end deftypefun
+
+@comment string.h
+@comment BSD
+@deftypefun {char *} strsep (char **@var{string_ptr}, const char *@var{delimiter})
+A second reentrant approach is to avoid the additional first argument.
+The initialization of the moving pointer has to be done by the user.
+Successive calls of @code{strsep} move the pointer along the tokens
+separated by @var{delimiter}, returning the address of the next token
+and updating @var{string_ptr} to point to the beginning of the next
+token.
+
+This function was introduced in 4.3BSD and therefore is widely available.
+@end deftypefun
