+ This variable contains the value of the LONGSIZE symbol,
+ which indicates to the C program how many bytes there are
+ in a long integer.

+
prefix (prefix.U):

user will install the package. Usually, this is /usr/local, and
This symbol contains the type of pointer returned by shmat().
It can be 'void *' or 'char *'.

+ This variable contains the value of the SHORTSIZE symbol,
+ which indicates to the C program how many bytes there are
+ in a short integer.
+
+shrpenv (libperl.U):
+ If the user builds a shared libperl.so, then we need to tell the
+ 'perl' executable where it will be able to find the installed libperl.so.
+ One way to do this on some systems is to set the environment variable
+ LD_RUN_PATH to the directory that will be the final location of the
+ shared libperl.so. The makefile can use this with something like
+ $shrpenv $(CC) -o perl perlmain.o $libperl $libs
+ Typical values are
+ shrpenv="env LD_RUN_PATH=$archlibexp/CORE"
+ or
+ shrpenv=''
+ See the main perl Makefile.SH for actual working usage.
+ Alternatively, we might be able to use a command line option such
+ as -R $archlibexp/CORE (Solaris, NetBSD) or -Wl,-rpath
+ $archlibexp/CORE (Linux).
+
sig_name (sig_name.U):
This variable holds the signal names, space separated. The leading
SIG in signals name is removed. See sig_num.
script to make sure (hopefully) that it runs with perl and not some
shell. Of course, that leading line must be followed by the classical
perl idiom:
- eval 'exec perl -S $0 "$@"'
+ eval 'exec /usr/bin/perl -S $0 ${1+"$@"}'
if $running_under_some_shell;
to guarantee perl startup should the shell execute the script. Note
that this magic incatation is not understood by csh.
