=head1 AVAILABILITY
Perl is available for most operating systems, including virtually
-all Unix-like platforms.
-
-As of May 1999, the following platforms are able to build Perl
-from the standard source code distribution available at
-http://www.perl.com/CPAN/src/index.html
-
- AIX Linux SCO ODT/OSR
- A/UX MachTen Solaris
- BeOS MPE/iX SunOS
- BSD/OS NetBSD SVR4
- DG/UX NextSTEP Tru64 UNIX 3)
- DomainOS OpenBSD Ultrix

- HP-UX PowerMAX Windows 3.1 1)
- Hurd QNX Windows 95 1) 4)
- IRIX Windows 98 1) 4)
- Windows NT 1) 4)
-
- 1) in DOS mode either the DOS or OS/2 ports can be used
- 2) formerly known as MVS
- 3) formerly known as Digital UNIX and before that DEC OSF/1
- 4) compilers: Borland, Cygwin32, Mingw32 EGCS/GCC, VC++
-
-The following platforms have been known to build Perl from source,
-but we haven't been able to verify their status for the current release,
-either because the hardware/software platforms are rare or
-because we don't have an active champion on these platforms--or both.

You may mail your bug reports (be sure to include full configuration
information as output by the myconfig program in the perl source
tree, or by C<perl -V>) to perlbug@perl.com . If you've succeeded
