_a (Unix.U):
This variable defines the extension used for ordinary library files.
_exe (Unix.U):
This variable defines the extension used for executable files.
DJGPP, Cygwin and OS/2 use '.exe'. Stratus VOS uses '.pm'.
- No other operating systems require an extension for executable
- files, so it is empty for all others.
+ On operating systems which do not require a specific extension
+ for executable files, this variable is empty.
_o (Unix.U):
This variable defines the extension used for object files.
is most often a local directory such as /usr/local/bin. Programs using
this variable must be prepared to deal with ~name substitution.
-bincompat5005 (bincompat5005.U):
- This variable contains y if this version of Perl should be
- binary-compatible with Perl 5.005.
-
binexp (bin.U):
This is the same as the bin variable, but is filename expanded at
configuration time, for use in your makefiles.
the value is reset to a plain "byacc" and is not useful.
byteorder (byteorder.U):
- This variable holds the byte order. In the following, larger digits
- indicate more significance. The variable byteorder is either 4321
- on a big-endian machine, or 1234 on a little-endian, or 87654321
- on a Cray ... or 3412 with weird order !

c (n.U):
This variable contains the \c string if that is what causes the echo
This variable conditionally defines the HAS_BCOPY symbol if
the bcopy() routine is available to copy strings.
-d_bincompat5005 (bincompat5005.U):
- This variable conditionally defines BINCOMPAT5005 so that embed.h
- can take special action if this version of Perl should be
- binary-compatible with Perl 5.005. This is impossible for builds
- that use features like threads and multiplicity it is always $undef

d_bsd (Guess.U):
This symbol conditionally defines the symbol BSD when running on a
BSD system.

the value is reset to a plain "make" and is not useful.
- Both the directory and the command name can vary from system
- to system; while most systems call the command 'make', other
- values include 'gmake' and 'gnumake'.
-
make_set_make (make.U):
Some versions of 'make' set the variable MAKE. Others do not.
This variable contains the string to be included in Makefile.SH
installed perl5.005 or later suitable for running the script
to determine inc_version_list.
-perl5 (perl5.U):
- This variable contains the full path (if any) to a previously
- installed perl5.005 or later suitable for running the script
- to determine inc_version_list.
-
perl (Loc.U):
This variable is defined but not used by Configure.
The value is a plain '' and is not useful.
See INSTALL for how this works.
The versioned site_perl directory was introduced in 5.005,
so that is the lowest possible value.

of potential incompatibility, such as multiplicity, threads,
debugging, 64bits, sfio, etc., are not checked for currently,

Config.pm files.
+yacc (yacc.U):
+ This variable holds the name of the compiler compiler we
+ want to use in the Makefile. It can be yacc, byacc, or bison -y.

yaccflags (yacc.U):
This variable contains any additional yacc flags desired by the
user. It is up to the Makefile to use this.
