3030 * This symbol indicates how much support of the void type is given by this
3031 * compiler. What various bits mean:
3033 * 1 = supports declaration of void
3034 * 2 = supports arrays of pointers to functions returning void
3035 * 4 = supports comparisons between pointers to void functions and
3036 * addresses of void functions
3037 * 8 = suports declaration of generic void pointers
3039 * The package designer should define VOIDUSED to indicate the requirements
3040 * of the package. This can be done either by #defining VOIDUSED before
3041 * including config.h, or by defining defvoidused in Myinit.U. If the
3042 * latter approach is taken, only those flags will be tested. If the
3043 * level of void support necessary is not present, defines void to int.

3054 /* PERL_XS_APIVERSION:
3055 * This variable contains the version of the oldest perl binary
3056 * compatible with the present perl. perl.c:incpush() and
3057 * lib/lib.pm will automatically search in $sitearch for older
3058 * directories across major versions back to xs_apiversion.
3059 * This is only useful if you have a perl library directory tree
3060 * structured like the default one.
3061 * See INSTALL for how this works.
3062 * The versioned site_perl directory was introduced in 5.005,
3063 * so that is the lowest possible value.
3064 * Since this can depend on compile time options (such as
3065 * bincompat) it is set by Configure. Other non-default sources
3066 * of potential incompatibility, such as multiplicity, threads,
3067 * debugging, 64bits, sfio, etc., are not checked for currently,
3068 * though in principle we could go snooping around in old
3071 /* PERL_PM_APIVERSION:
3072 * This variable contains the version of the oldest perl
3073 * compatible with the present perl. (That is, pure perl modules
3074 * written for pm_apiversion will still work for the current
3075 * version). perl.c:incpush() and lib/lib.pm will automatically
3076 * search in $sitelib for older directories across major versions
3077 * back to pm_apiversion. This is only useful if you have a perl
3078 * library directory tree structured like the default one. The
3079 * versioned site_perl library was introduced in 5.005, so that's
3080 * the default setting for this variable. It's hard to imagine
3081 * it changing before Perl6. It is included here for symmetry
3082 * with xs_apiveprsion -- the searching algorithms will
3083 * (presumably) be similar.
3084 * See the INSTALL file for how this works.
