3079 * The package designer should define VOIDUSED to indicate the requirements
3080 * of the package. This can be done either by #defining VOIDUSED before
3081 * including config.h, or by defining defvoidused in Myinit.U. If the
3082 * latter approach is taken, only those flags will be tested. If the
3083 * level of void support necessary is not present, defines void to int.

3094 /* PERL_XS_APIVERSION:
3095 * This variable contains the version of the oldest perl binary
3096 * compatible with the present perl. perl.c:incpush() and
3097 * lib/lib.pm will automatically search in for older
3098 * directories across major versions back to xs_apiversion.
3099 * This is only useful if you have a perl library directory tree
3100 * structured like the default one.
3101 * See INSTALL for how this works.
3102 * The versioned site_perl directory was introduced in 5.005,
3103 * so that is the lowest possible value.
3104 * Since this can depend on compile time options (such as
3105 * bincompat) it is set by Configure. Other non-default sources
3106 * of potential incompatibility, such as multiplicity, threads,
3107 * debugging, 64bits, sfio, etc., are not checked for currently,
3108 * though in principle we could go snooping around in old
3111 /* PERL_PM_APIVERSION:
3112 * This variable contains the version of the oldest perl
3113 * compatible with the present perl. (That is, pure perl modules
3114 * written for pm_apiversion will still work for the current
3115 * version). perl.c:incpush() and lib/lib.pm will automatically
3116 * search in for older directories across major versions
3117 * back to pm_apiversion. This is only useful if you have a perl
3118 * library directory tree structured like the default one. The
3119 * versioned site_perl library was introduced in 5.005, so that's
3120 * the default setting for this variable. It's hard to imagine
3121 * it changing before Perl6. It is included here for symmetry
3122 * with xs_apiveprsion -- the searching algorithms will
3123 * (presumably) be similar.
3124 * See the INSTALL file for how this works.
