3 * VIM - Vi IMproved by Bram Moolenaar
5 * Do ":help uganda" in Vim to read copying and usage conditions.
6 * Do ":help credits" in Vim to see a list of people who contributed.
9 * if_perl.xs: Main code for Perl interface support.
10 * Mostly written by Sven Verdoolaege.
13 #define _memory_h /* avoid memset redeclaration */
14 #define IN_PERL_FILE /* don't include if_perl.pro from proto.h */
20 * Work around clashes between Perl and Vim namespace. proto.h doesn't
21 * include if_perl.pro and perlsfio.pro when IN_PERL_FILE is defined, because
22 * we need the CV typedef. proto.h can't be moved to after including
23 * if_perl.h, because we get all sorts of name clashes then.
27 # include "proto/if_perl.pro"
28 # include "proto/if_perlsfio.pro"
32 /* Perl compatibility stuff. This should ensure compatibility with older
37 # include <patchlevel.h>
38 # define PERL_REVISION 5
39 # define PERL_VERSION PATCHLEVEL
40 # define PERL_SUBVERSION SUBVERSION
44 * Quoting Jan Dubois of Active State:
45 * ActivePerl build 822 still identifies itself as 5.8.8 but already
46 * contains many of the changes from the upcoming Perl 5.8.9 release.
48 * The changes include addition of two symbols (Perl_sv_2iv_flags,
49 * Perl_newXS_flags) not present in earlier releases.
51 * Jan Dubois suggested the following guarding scheme.
53 * Active State defined ACTIVEPERL_VERSION as a string in versions before
54 * 5.8.8; and so the comparison to 822 below needs to be guarded.
