which indicates to the C program that the system provides
This variable conditionally defines HAS_SYSCALL if syscall() is
available call arbitrary system calls.
+d_syscallproto (d_syscallproto.U):
+ This variable conditionally defines the HAS_SYSCALL_PROTO symbol,
+ which indicates to the C program that the system provides
+ a prototype for the syscall() function. Otherwise, it is
+ up to the program to supply one.
+
d_sysconf (d_sysconf.U):
This variable conditionally defines the HAS_SYSCONF symbol, which
indicates to the C program that the sysconf() routine is available
This variable conditionally defines HAS_USLEEP if usleep() is
available to do high granularity sleeps.
+d_usleepproto (d_usleepproto.U):
+ This variable conditionally defines the HAS_USLEEP_PROTO symbol,
+ which indicates to the C program that the system provides
+ a prototype for the usleep() function. Otherwise, it is
+ up to the program to supply one.
+
d_ustat (d_ustat.U):
This variable conditionally defines HAS_USTAT if ustat() is
available to query file system statistics by dev_t.
This variable contains the return type of free(). It is usually
void, but occasionally int.
+from (Cross.U):
+ This variable contains the command used by Configure
+ to copy files from the target host. Useful and available
+ only during Perl build.
+ The string ':' if not cross-compiling.
+
full_ar (Loc_ar.U):
This variable contains the full pathname to 'ar', whether or
not the user has specified 'portability'. This is only used
This variable is defined but not used by Configure.
The value is a plain '' and is not useful.
+run (Cross.U):
+ This variable contains the command used by Configure
+ to copy and execute a cross-compiled executable in the
+ target host. Useful and available only during Perl build.
+ Empty string '' if not cross-compiling.
+
runnm (usenm.U):
This variable contains 'true' or 'false' depending whether the
nm extraction should be performed or not, according to the value
This variable is defined but not used by Configure.
The value is a plain '' and is not useful.
+targetarch (Cross.U):
+ If cross-compiling, this variable contains the target architecture.
+ If not, this will be empty.
+
tbl (Loc.U):
This variable is defined but not used by Configure.
The value is a plain '' and is not useful.
or time_t on BSD sites (in which case <sys/types.h> should be
included). Anyway, the type Time_t should be used.
+to (Cross.U):
+ This variable contains the command used by Configure
+ to copy to from the target host. Useful and available
+ only during Perl build.
+ The string ':' if not cross-compiling.
+
touch (Loc.U):
This variable is used internally by Configure to determine the
full pathname (if any) of the touch program. After Configure runs,
This may mean using for example "long longs", while your memory
may still be limited to 2 gigabytes.
+usecrosscompile (Cross.U):
+ This variable conditionally defines the USE_CROSS_COMPILE symbol,
+ and indicates that Perl has been cross-compiled.

on a particular system.
+usereentrant (usethreads.U):
+ This variable conditionally defines the USE_REENTRANT_API symbol,
+ which indicates that the thread code may try to use the various
+ _r versions of library functions. This is only potentially
+ meaningful if usethreads is set and is very experimental, it is
+ not even prompted for.
+
usesfio (d_sfio.U):
This variable is set to true when the user agrees to use sfio.
It is set to false when sfio is not available or when the user
