3086 * 1 = supports declaration of void
3087 * 2 = supports arrays of pointers to functions returning void

3116 * so that is the lowest possible value.
3117 * Since this can depend on compile time options (such as
3118 * bincompat) it is set by Configure. Other non-default sources
3119 * of potential incompatibility, such as multiplicity, threads,

3124 /* PERL_PM_APIVERSION:
3125 * This variable contains the version of the oldest perl
3126 * compatible with the present perl. (That is, pure perl modules
3127 * written for pm_apiversion will still work for the current
3128 * version). perl.c:incpush() and lib/lib.pm will automatically
3129 * search in $sitelib for older directories across major versions
3130 * back to pm_apiversion. This is only useful if you have a perl
3131 * library directory tree structured like the default one. The
3132 * versioned site_perl library was introduced in 5.005, so that's
3133 * the default setting for this variable. It's hard to imagine
3134 * it changing before Perl6. It is included here for symmetry
3135 * with xs_apiveprsion -- the searching algorithms will
3136 * (presumably) be similar.
3137 * See the INSTALL file for how this works.
