2973 * 8 = suports declaration of generic void pointers
2975 * The package designer should define VOIDUSED to indicate the requirements
2976 * of the package. This can be done either by #defining VOIDUSED before
2977 * including config.h, or by defining defvoidused in Myinit.U. If the
2978 * latter approach is taken, only those flags will be tested. If the
2979 * level of void support necessary is not present, defines void to int.

2990 /* PERL_XS_APIVERSION:
2991 * This variable contains the version of the oldest perl binary
2992 * compatible with the present perl. perl.c:incpush() and
2993 * lib/lib.pm will automatically search in $sitearch for older
2994 * directories across major versions back to xs_apiversion.
2995 * This is only useful if you have a perl library directory tree
2996 * structured like the default one.
2997 * See INSTALL for how this works.
2998 * The versioned site_perl directory was introduced in 5.005,
2999 * so that is the lowest possible value.
3000 * Since this can depend on compile time options (such as
3001 * bincompat) it is set by Configure. Other non-default sources
3002 * of potential incompatibility, such as multiplicity, threads,
3003 * debugging, 64bits, sfio, etc., are not checked for currently,
3004 * though in principle we could go snooping around in old
3007 /* PERL_PM_APIVERSION:
3008 * This variable contains the version of the oldest perl
3009 * compatible with the present perl. (That is, pure perl modules
3010 * written for pm_apiversion will still work for the current
3011 * version). perl.c:incpush() and lib/lib.pm will automatically
3012 * search in $sitelib for older directories across major versions
3013 * back to pm_apiversion. This is only useful if you have a perl
3014 * library directory tree structured like the default one. The
3015 * versioned site_perl library was introduced in 5.005, so that's
3016 * the default setting for this variable. It's hard to imagine
3017 * it changing before Perl6. It is included here for symmetry
3018 * with xs_apiveprsion -- the searching algorithms will
3019 * (presumably) be similar.
3020 * See the INSTALL file for how this works.
