apart a string, and supports some text substitutions. This can be
used to provide all the flexibility (and more!) that was lost by recent
changes to how the kernel parses #!-lines in shell scripts.
The '-P' option provides a way to specify an alternate set of directories
to use when searching for the 'utility' program to run. This way you can
be sure what directories are used for that search, without changing the
value of PATH that the user has set. Note that on FreeBSD 6.0, this
option is worthless unless the '-S' option is also used.

without checking it for an equals-sign. If it starts with a slash, then
it cannot be a request to set the value of a valid environment variable.

it does not happen until all single-letter options are processed. This will
be important for the -S option, which will be coming soon.

malloc(9) statistics from kernel memory or a kernel coredump, to catch
up with recent changes to adopt per-CPU malloc(9) statistics. The new
routines walk the per-CPU statistics pools and coalesce them for
presentation to the user.
the string. Until now this caused no harm, because the buffer code used
to tack two NULs onto buffers. With the new, soon to come, parsing code
this isn't the case anymore in all cases, so fix this.
rename the function to be consistent with the naming scheme in the rest
of make. No functional changes.

before executing the shell. Until now this was done when the default
shell was the ksh. This failed if the default shell was sh or csh and
the user switched to ksh.
set the current shell to DEFSHELL. Put all these specifications into
a list. Add user specified new shells to this list. If the user
just selects one of the already know shells just pick the right one
off the list. This let's one do something like:
# Full specification of the user's shell. This also selects the shell.
.SHELL: name=myshell path=/somewhere/foo echo=loud ...
FOO != bar # use myshell here
.SHELL: name=sh
BAR != baz # use /bin/sh here
.SHELL: name=myshell # no need for full spec here.
# continue to use the user's special shell.
the list of shell builtins. Both of these are needed for the compat
mode where make directly executes commands if the command line contains
neither a shell meta character nor a shell builtin. The list of builtins
is not changed, but csh has '@' added as a meta-character.
Initialize the default shell by parsing a string as one would specify
to the .SHELL target. So we get rid of the CShell clone of struct Shell which
just contained const char * where struct Shell had char *.
Add a debugging function for dumping a parsed shell description to
stdout.
introduce a struct that holds all the information about an argument
vector and pass that around.

This saves 6 more columns in 80-column terminals, making things a lot
better for the COMMAND column.
