3088 * Vendors who distribute perl may wish to place their own
3089 * architecture-dependent modules and extensions in this directory with
3090 * MakeMaker Makefile.PL INSTALLDIRS=vendor
3091 * or equivalent. See INSTALL for details.
3093 /* PERL_VENDORARCH_EXP:
3094 * This symbol contains the ~name expanded version of PERL_VENDORARCH, to be used
3095 * in programs that are not prepared to deal with ~ expansion at run-time.
3097 /*#define PERL_VENDORARCH "" / **/
3098 /*#define PERL_VENDORARCH_EXP "" / **/
3100 /* PERL_VENDORLIB_EXP:
3101 * This symbol contains the ~name expanded version of VENDORLIB, to be used
3102 * in programs that are not prepared to deal with ~ expansion at run-time.
3104 /* PERL_VENDORLIB_STEM:
3105 * This define is PERL_VENDORLIB_EXP with any trailing version-specific component
3106 * removed. The elements in inc_version_list (inc_version_list.U) can
3107 * be tacked onto this variable to generate a list of directories to search.

3110 /*#define PERL_VENDORLIB_STEM "" / **/
3113 * This symbol indicates how much support of the void type is given by this
3114 * compiler. What various bits mean:
3116 * 1 = supports declaration of void
3117 * 2 = supports arrays of pointers to functions returning void
3118 * 4 = supports comparisons between pointers to void functions and
3119 * addresses of void functions
3120 * 8 = suports declaration of generic void pointers
3122 * The package designer should define VOIDUSED to indicate the requirements
3123 * of the package. This can be done either by #defining VOIDUSED before
3124 * including config.h, or by defining defvoidused in Myinit.U. If the
3125 * latter approach is taken, only those flags will be tested. If the
3126 * level of void support necessary is not present, defines void to int.
3132 #if (VOIDFLAGS & VOIDUSED) != VOIDUSED
3133 #define void int /* is void to be avoided? */
3134 #define M_VOID /* Xenix strikes again */
3137 /* PERL_XS_APIVERSION:
3138 * This variable contains the version of the oldest perl binary
3139 * compatible with the present perl. perl.c:incpush() and
3140 * lib/lib.pm will automatically search in for older
3141 * directories across major versions back to xs_apiversion.
3142 * This is only useful if you have a perl library directory tree
3143 * structured like the default one.
3144 * See INSTALL for how this works.
3145 * The versioned site_perl directory was introduced in 5.005,
3146 * so that is the lowest possible value.
3147 * Since this can depend on compile time options (such as
3148 * bincompat) it is set by Configure. Other non-default sources
3149 * of potential incompatibility, such as multiplicity, threads,
3150 * debugging, 64bits, sfio, etc., are not checked for currently,
3151 * though in principle we could go snooping around in old
3154 /* PERL_PM_APIVERSION:
3155 * This variable contains the version of the oldest perl
3156 * compatible with the present perl. (That is, pure perl modules
3157 * written for pm_apiversion will still work for the current
3158 * version). perl.c:incpush() and lib/lib.pm will automatically
3159 * search in for older directories across major versions
3160 * back to pm_apiversion. This is only useful if you have a perl
3161 * library directory tree structured like the default one. The
3162 * versioned site_perl library was introduced in 5.005, so that's
3163 * the default setting for this variable. It's hard to imagine
3164 * it changing before Perl6. It is included here for symmetry
3165 * with xs_apiveprsion -- the searching algorithms will
3166 * (presumably) be similar.
3167 * See the INSTALL file for how this works.
