round has been tested on Solaris/x86 and Linux hosts.
* Add host tools cap_mkdb, ctags, m4, uudecode.
* Protect __RCSID() and __COPYRIGHT() better.
* Reduce the number of places that need to include "config.h", to keep
sources closer to their "vanilla" versions.
* Add more compat #defines and autoconf-checked functions.

When looking up names which directory components (i.e. having slashes,
except when of the form `./name'), FindFile()/DirLookup() first looks
the final filename component in the cache for each directory on the search
path and then proceeds to match the prefixed directory components by
comparing them to the trailing directory components of the the search
path being probed.
This is not correct. When looking for `bar/target' in a path `.../src/foo',
you want it to come up with `.../src/foo/bar/target' (if it exists). There's
no point in comparing the the `bar' prefix on the target to the `foo' suffix
on the search path. Indeed, this will cause a false match if those prefix
and suffix components are actually equal and search path itself also has a
file called `target'. For example, looking for `foo/target' in `.../src/foo'
will spuriously match `.../src/foo/target', not `.../src/foo/foo/target'.
This last bug prompted the change in dir.c, rev 1.27, which happens
to partially workaround it by avoiding the above matching code in the
case of the `curdir' search path entry (at the cost of incurring an
exorbitant amount of cache misses). The situation is unchanged however,
when processing other entries on the search path (e.g. those other than
`dot' and `cur').
Drop the prefix matching code in DirLookup() entirely and use DirFindDot()
and DirLookup() only for names without proper directory components (i.e.
`target' and `./target). Otherwise, non-absolute names are dealt with by
DirLookupSubdir(), while absolute names can be checked for an exact match
of the directory components prefix against the directories on the current
search path. This allows for the use of the file cache to check the
existence of the file and additionally, provides a shortcut out of
Dir_FindFile() if we have the prefix match but not a cache entry (this
is especially beneficial for searches in .CURDIR when it's not equal
to `dot').
if the stdout was same as the audio device. It's no longer relevant,
and the check was broken anyway (code used st_dev rather than st_rdev
when comparing the character devices).
A by-product of this is that 'audioctl -a > /dev/null' now works.
Okay'ed by Lennart.
the .DOTLAST primitive by a boolean variable with the same name, this whole
mechanism was broken ... it doesn't save much stat calls but it was wrong.
Thanks to Jason Thorpe for the other shadow-variable fixing patches he
made.
foo\:bar:
touch $@
works. Of course I am lazy right now, and I am not removing the '\' escapes
so the output looks fine, but it is functionally correct.
