+IMPORTANT NOTE: 5.005_53 and later releases do not export unadorned
+global symbols anymore. This means most CPAN modules probably won't
+build under this release without adding '-DPERL_POLLUTE' to ccflags
+in config.sh. This is not the default because we want the modules
+to get fixed *before* the 5.006 release. pod/perldelta.pod contains
+additional notes about this.

+=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.

into a directory typically found along a user's PATH, or in another
obvious and convenient place.
+You can use "Configure -Uinstallusrbinperl" which causes installperl
+to skip installing perl also as /usr/bin/perl.

By default, Configure will compile perl to use dynamic loading if
your system supports it. If you want to force perl to be compiled
statically, you can either choose this when Configure prompts you or

+but you still want Configure to find it. To be specific, assume you
have /usr/you/include/gdbm.h and /usr/you/lib/libgdbm.a. You
still have to add -I/usr/you/include to cc flags, but you have to take
an extra step to help Configure find libgdbm.a. Specifically, when
process, you can answer a question with &-d and Configure
will use the defaults from then on.
-By default, Configure will use the following directories for

=head2 Site-wide Policy settings
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:
-
- sh Configure -Dccflags='-Drand=random -Dsrand=srandom'
-
-or by adding -Drand=random and -Dsrand=srandom to your ccflags
-at the appropriate Configure prompt. (Note: Although this worked for
-me, it might not work for you if your system's header files give
-different prototypes for rand() and random() or srand() and srandom().)
+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

bval settings. Upgrade your DB library or OS.
+=item Bad arg length for semctl, is XX, should be ZZZ
+
+If you get this error message from the lib/ipc_sysv test, your System
+V IPC may be broken. The XX typically is 20, and that is what ZZZ
+also should be. Consider upgrading your OS, or reconfiguring your OS
+to include the System V semaphores.
+
+=item lib/ipc_sysv........semget: No space left on device
+
+Either your account or the whole system has run out of semaphores. Or
+both. Either list the semaphores with "ipcs" and remove the unneeded
+ones (which ones these are depends on your system and applications)
+with "ipcrm -s SEMAPHORE_ID_HERE" or configure more semaphores to your
+system.
+
=item Miscellaneous
Some additional things that have been reported for either perl4 or perl5:
UTS may need one or more of -DCRIPPLED_CC, -K or -g, and undef LSTAT.
+FreeBSD can fail the lib/ipc_sysv.t test if SysV IPC has not been
+configured to the kernel. Perl tries to detect this, though, and
+you will get a message telling what to do.

If you get syntax errors on '(', try -DCRIPPLED_CC.
Machines with half-implemented dbm routines will need to #undef I_ODBM
Installperl will also create the library directories $siteperl and
$sitearch listed in config.sh. Usually, these are something like
- /usr/local/lib/perl5/site_perl/5.005/share
+ /usr/local/lib/perl5/site_perl/5.005
/usr/local/lib/perl5/site_perl/5.005/archname
