3165 * It may have a ~ on the front.

3192 * This symbol indicates how much support of the void type is given by this
3193 * compiler. What various bits mean:
3195 * 1 = supports declaration of void
3196 * 2 = supports arrays of pointers to functions returning void
3197 * 4 = supports comparisons between pointers to void functions and
3198 * addresses of void functions
3199 * 8 = suports declaration of generic void pointers
3201 * The package designer should define VOIDUSED to indicate the requirements
3202 * of the package. This can be done either by #defining VOIDUSED before
3203 * including config.h, or by defining defvoidused in Myinit.U. If the
3204 * latter approach is taken, only those flags will be tested. If the
3205 * level of void support necessary is not present, defines void to int.

3216 /* PERL_XS_APIVERSION:
3217 * This variable contains the version of the oldest perl binary
3218 * compatible with the present perl. perl.c:incpush() and
3219 * lib/lib.pm will automatically search in for older
3220 * directories across major versions back to xs_apiversion.
3221 * This is only useful if you have a perl library directory tree
3222 * structured like the default one.
3223 * See INSTALL for how this works.
3224 * The versioned site_perl directory was introduced in 5.005,
3225 * so that is the lowest possible value.
3226 * Since this can depend on compile time options (such as
3227 * bincompat) it is set by Configure. Other non-default sources
3228 * of potential incompatibility, such as multiplicity, threads,
3229 * debugging, 64bits, sfio, etc., are not checked for currently,
3230 * though in principle we could go snooping around in old
3233 /* PERL_PM_APIVERSION:
3234 * This variable contains the version of the oldest perl
3235 * compatible with the present perl. (That is, pure perl modules
3236 * written for pm_apiversion will still work for the current
3237 * version). perl.c:incpush() and lib/lib.pm will automatically
3238 * search in for older directories across major versions
3239 * back to pm_apiversion. This is only useful if you have a perl
3240 * library directory tree structured like the default one. The
3241 * versioned site_perl library was introduced in 5.005, so that's
3242 * the default setting for this variable. It's hard to imagine
3243 * it changing before Perl6. It is included here for symmetry
3244 * with xs_apiveprsion -- the searching algorithms will
3245 * (presumably) be similar.
3246 * See the INSTALL file for how this works.
