this variable must be prepared to deal with ~name substitution.
+bincompat3 (bincompat3.U):
+ This variable contains y if Perl 5.004 should be binary-compatible
+ with Perl 5.003.
+
byteorder (byteorder.U):
This variable holds the byte order. In the following, larger digits
indicate more significance. The variable byteorder is either 4321
This variable conditionally defines the HAS_BCOPY symbol if
the bcopy() routine is available to copy strings.
+d_bincompat3 (bincompat3.U):
+ This variable conditionally defines BINCOMPAT3 so that embed.h
+ can take special action if Perl 5.004 should be binary-compatible
+ with Perl 5.003.
+
d_bsdgetpgrp (d_getpgrp.U):
This variable conditionally defines USE_BSD_GETPGRP if
getpgrp needs one arguments whereas USG one needs none.
This variable conditionally defines HAS_FSETPOS if fsetpos() is
available to set the file position indicator.
+d_ftime (d_ftime.U):

+ indicates that the ftime() routine exists. The ftime() routine is
+ basically a sub-second accuracy clock.
+
d_gethent (d_gethent.U):
This variable conditionally defines HAS_GETHOSTENT if gethostent() is
available to dup file descriptors.
+d_gettimeod (d_ftime.U):
+ This variable conditionally defines the HAS_GETTIMEOFDAY symbol, which
+ indicates that the gettimeofday() system call exists (to obtain a
+ sub-second accuracy clock).
+
d_getlogin (d_getlogin.U):
This variable conditionally defines the HAS_GETLOGIN symbol, which
indicates to the C program that the getlogin() routine is available
This variable conditionally defines HAS_INDEX if index() and
rindex() are available for string searching.
+d_inetaton (d_inetaton.U):
+ This variable conditionally defines the HAS_INET_ATON symbol, which
+ indicates to the C program that the inet_aton() function is available
+ to parse IP address "dotted-quad" strings.
+
d_isascii (d_isascii.U):
This variable conditionally defines the HAS_ISASCII constant,
which indicates to the C program that isascii() is available.
This variable conditionally defines the HAS_SAFE_MEMCPY symbol if
the memcpy() routine can do overlapping copies.
+d_sanemcmp (d_sanemcmp.U):
+ This variable conditionally defines the HAS_SANE_MEMCMP symbol if
+ the memcpy() routine is available and can be used to compare relative
+ magnitudes of chars with their high bits set.
+
d_seekdir (d_readdir.U):
This variable conditionally defines HAS_SEEKDIR if seekdir() is
available.
This variable conditionally defines HAS_STRERROR if strerror() is
available to translate error numbers to strings.
+d_strtod (d_strtod.U):
+ This variable conditionally defines the HAS_STRTOD symbol, which
+ indicates to the C program that the strtod() routine is available
+ to provide better numeric string conversion than atof().
+
+d_strtol (d_strtol.U):
+ This variable conditionally defines the HAS_STRTOL symbol, which
+ indicates to the C program that the strtol() routine is available
+ to provide better numeric string conversion than atoi() and friends.
+
+d_strtoul (d_strtoul.U):
+ This variable conditionally defines the HAS_STRTOUL symbol, which
+ indicates to the C program that the strtoul() routine is available
+ to provide conversion of strings to unsigned long.
+
d_strxfrm (d_strxfrm.U):
This variable conditionally defines HAS_STRXFRM if strxfrm() is
available to transform strings.
perladmin (perladmin.U):
Electronic mail address of the perl5 administrator.
+perlpath (perlpath.U):
+ This variable contains the eventual value of the PERLPATH symbol,
+ which contains the name of the perl interpreter to be used in
+ shell scripts and in the "eval 'exec'" idiom.
+
prefix (prefix.U):
This variable holds the name of the directory below which the
user will install the package. Usually, this is /usr/local, and
