occurances of these calls and report them (they're bugs).
Use the TERMINATE function in the strncpy version of SAFECOPY()
(does it need the int-typecast Deuce?).

(bugs found by Deuce ala Valgrind).

on the passed path...
For fexist() simply return TRUE if access()!=-1 && !isdir()
For fexistcase() *try* the access()/isdir() method first, then do the full
search.  Should make a reasonable difference.  Profileing suggests that
iniFileName() is quite slow due to the fexistcase() calls.  As the general
case is that the passed path is correct, this should speed up most calls
to fexist*().

LDFLAGS from being reflected in UTIL_LDFLAGS.

No longer use socket_check() to check for readability as the recv() call
in there was using up over 30% of the CPU time.

name or alias. More sanity checking of the RLogin-supplied "password" is
probably prudent here (Deuce?).

PROFILE		Builds a profiled version suitable for use with gprof
		This option is only usefull for developers.
		(On most systems, the profile libraries don't exist, so this
		 will fail)
UPROFILE	Generates data for profile-based optimizations.
		Can be used to generate heavily optimized builds... but is
		not trivial to use and does use extra disk space.  Expert
		users only.
GCOV		Generates data for usage by gcov.  Only usefull for developers.
USE_UPROFILE	Uses the UPROFILE generated data for more optimizations.

listShiftNode macros) for complete thread-safety.

Previous commit also included micro-optimizations... SAFECOPY() now uses
strncpy() then terminates.  *BSD doesn't need to TERMINATE() snprintf().

Introduced LAST_NODE macro to use in push/pop macros for thread-safe list
modifications (can't use listLastNode function).
