3082 * The standard distribution will put nothing in this directory.
3083 * Vendors who distribute perl may wish to place their own
3084 * architecture-dependent modules and extensions in this directory with

3086 * or equivalent. See INSTALL for details.
3088 /* PERL_VENDORARCH_EXP:
3089 * This symbol contains the ~name expanded version of PERL_VENDORARCH, to be used
3090 * in programs that are not prepared to deal with ~ expansion at run-time.

3095 /* PERL_VENDORLIB_EXP:
3096 * This symbol contains the ~name expanded version of VENDORLIB, to be used
3097 * in programs that are not prepared to deal with ~ expansion at run-time.
3099 /* PERL_VENDORLIB_STEM:
3100 * This define is PERL_VENDORLIB_EXP with any trailing version-specific component
3101 * removed. The elements in inc_version_list (inc_version_list.U) can
3102 * be tacked onto this variable to generate a list of directories to search.

3108 * This symbol indicates how much support of the void type is given by this
3109 * compiler. What various bits mean:
3111 * 1 = supports declaration of void
3112 * 2 = supports arrays of pointers to functions returning void
3113 * 4 = supports comparisons between pointers to void functions and
3114 * addresses of void functions
3115 * 8 = suports declaration of generic void pointers
3117 * The package designer should define VOIDUSED to indicate the requirements
3118 * of the package. This can be done either by #defining VOIDUSED before
3119 * including config.h, or by defining defvoidused in Myinit.U. If the
3120 * latter approach is taken, only those flags will be tested. If the
3121 * level of void support necessary is not present, defines void to int.
3127 #if (VOIDFLAGS & VOIDUSED) != VOIDUSED
3128 #define void int /* is void to be avoided? */
3129 #define M_VOID /* Xenix strikes again */
3132 /* PERL_XS_APIVERSION:
3133 * This variable contains the version of the oldest perl binary
3134 * compatible with the present perl. perl.c:incpush() and
3135 * lib/lib.pm will automatically search in for older
3136 * directories across major versions back to xs_apiversion.
3137 * This is only useful if you have a perl library directory tree
3138 * structured like the default one.
3139 * See INSTALL for how this works.
3140 * The versioned site_perl directory was introduced in 5.005,
3141 * so that is the lowest possible value.
3142 * Since this can depend on compile time options (such as
3143 * bincompat) it is set by Configure. Other non-default sources
3144 * of potential incompatibility, such as multiplicity, threads,
3145 * debugging, 64bits, sfio, etc., are not checked for currently,
3146 * though in principle we could go snooping around in old
3149 /* PERL_PM_APIVERSION:
3150 * This variable contains the version of the oldest perl
3151 * compatible with the present perl. (That is, pure perl modules
3152 * written for pm_apiversion will still work for the current
3153 * version). perl.c:incpush() and lib/lib.pm will automatically
3154 * search in for older directories across major versions
3155 * back to pm_apiversion. This is only useful if you have a perl
3156 * library directory tree structured like the default one. The
3157 * versioned site_perl library was introduced in 5.005, so that's
3158 * the default setting for this variable. It's hard to imagine
3159 * it changing before Perl6. It is included here for symmetry
3160 * with xs_apiveprsion -- the searching algorithms will
3161 * (presumably) be similar.
3162 * See the INSTALL file for how this works.

3211 * This symbol, if defined, indicates that the system provides
3212 * a prototype for the sbrk() function. Otherwise, it is up
3213 * to the program to supply one. Good guesses are
3214 * extern void* sbrk _((int));
3215 * extern void* sbrk _((size_t));

3220 * This symbol, if defined, indicates that the system stores
3221 * the variable argument list datatype, va_list, in a format
3222 * that cannot be copied by simple assignment, so that some
3223 * other means must be used when copying is required.
3224 * As such systems vary in their provision (or non-provision)
3225 * of copying mechanisms, handy.h defines a platform-
3226 * independent macro, Perl_va_copy(src, dst), to do the job.
