- when available. The maximal possible
- 64-bitness is employed: LP64 or ILP64, meaning that you will
- be able to use more than 2 gigabytes of memory. This mode is
- even more binary incompatible than USE_64_BITS. You may not
- be able to run the resulting executable in a 32-bit CPU at all or
- you may need at least to reboot your OS to 64-bit mode.

useithreads (usethreads.U):
This variable conditionally defines the USE_ITHREADS symbol,
and indicates that Perl should be built to use the interpreter-based
uvxformat (perlxvf.U):
This variable contains the format string used for printing
- a Perl UV as an unsigned hexadecimal integer.
+ a Perl UV as an unsigned hexadecimal integer in lowercase abcdef.
+
+uvXUformat (perlxvf.U):
+ This variable contains the format string used for printing
+ a Perl UV as an unsigned hexadecimal integer in uppercase ABCDEF.
+
+vendorarch (vendorarch.U):
+ This variable contains the value of the PERL_VENDORARCH symbol.
+ It may have a ~ on the front.
+ The standard distribution will put nothing in this directory.
+ Vendors who distribute perl may wish to place their own
+ architecture-dependent modules and extensions in this directory with
+ MakeMaker Makefile.PL INSTALLDIRS=vendor
+ or equivalent. See INSTALL for details.
+
+vendorarchexp (vendorarch.U):
+ This variable is the ~name expanded version of vendorarch, so that you
+ may use it directly in Makefiles or shell scripts.
vendorbin (vendorbin.U):
This variable contains the eventual value of the VENDORBIN symbol.
MakeMaker Makefile.PL INSTALLDIRS=vendor
or equivalent. See INSTALL for details.
+vendorlib_stem (vendorlib.U):
+ This variable is $vendorlibexp with any trailing version-specific component
+ removed. The elements in inc_version_list (inc_version_list.U) can
+ be tacked onto this variable to generate a list of directories to search.
+
vendorlibexp (vendorlib.U):
This variable is the ~name expanded version of vendorlib, so that you
may use it directly in Makefiles or shell scripts.
This is suitable for use as a directory name, and hence is
filesystem dependent.
+versiononly (versiononly.U):
+ If set, this symbol indicates that only the version-specific
+ components of a perl installation should be installed.
+ This may be useful for making a test installation of a new
+ version without disturbing the existing installation.
+ Setting versiononly is equivalent to setting installperl's -v option.
+ In particular, the non-versioned scripts and programs such as
+ a2p, c2ph, h2xs, pod2*, and perldoc are not installed
+ (see INSTALL for a more complete list). Nor are the man
+ pages installed.
+ Usually, this is undef.
+
vi (Loc.U):
This variable is defined but not used by Configure.
The value is a plain '' and is not useful.
