changes in the Perl language in the current release. Please see

+=head1 WARNING: This version requires a compiler that supports ANSI C.
+
+If you find that your C compiler is not ANSI-capable, try obtaining
+GCC, available from GNU mirrors worldwide (e.g. ftp://ftp.gnu.org/pub/gnu).
+Another alternative may be to use a tool like C<ansi2knr> to convert the
+sources back to K&R style, but there is no guarantee this route will get
+you anywhere, since the prototypes are not the only ANSI features used
+in the Perl sources. C<ansi2knr> is usually found as part of the freely
+available C<Ghostscript> distribution. Another similar tool is
+C<unprotoize>, distributed with GCC. Since C<unprotoize> requires GCC to
+run, you may have to run it on a platform where GCC is available, and move
+the sources back to the platform without GCC.
+
+If you succeed in automatically converting the sources to a K&R compatible
+form, be sure to email perlbug@perl.com to let us know the steps you
+followed. This will enable us to officially support this option.

=head1 Space Requirements
The complete perl5 source tree takes up about 10 MB of disk space. The
by adding appropriate -D directives to your ccflags variable in
config.sh.
-For example, you can replace the rand() and srand() functions in the
-perl source by any other random number generator by a trick such as the
-following (this should all be on one line):
-
- sh Configure -Dccflags='-Dmy_rand=random -Dmy_srand=srandom' \
- -Drandbits=31
-
-or you can use the drand48 family of functions with
-
- sh Configure -Dccflags='-Dmy_rand=lrand48 -Dmy_srand=srand48' \
- -Drandbits=31
-
-or by adding the -D flags to your ccflags at the appropriate Configure
-prompt. (Read pp.c to see how this works.)
+Starting from Perl 5.005_53 you no more need to replace the rand() and
+srand() functions in the perl source by any other random number
+generator because Configure chooses the widest one available
+(drand48(), srandom(), or rand()).
You should also run Configure interactively to verify that a hint file
doesn't inadvertently override your ccflags setting. (Hints files
