    + HB_ALERT(). Now this function holds all extended features:
      nDelay support and any type for first parameter.
    * ALERT() now behaves completely along Clipper version, without
      extensions. HB_EXTENSION no longer modifies its behaviour, so
      if someone needs these extended features, there is no need to
      build with HB_EXTENSION, only ALERT() calls have to be
      converted to HB_ALERT(). INCOMPATIBLE (in some scenarios).

  * contrib/hbtip/utils.c
    % TIP_TIMESTAMP() code cleaned to remove redundancy of
      having two full distinct copies of this function. Now
      platform independent parts are kept common.
    ! TIP_TIMESTAMP() fixed hb_parl() to hb_parnl() for 'hours'
      parameter. I wonder how this bug wasn't noticed till now.
      Please someone test, maybe I'm missing the point of this
      parameter, but it's unlikely the intent was a logical value
      as it's later converted to timestamp.

    * Minor formatting.

  * contrib/hbtip/base64x.c
  * contrib/hbtip/smtpcln.prg
    * Formatted.
    * Minor optimizations (File() -> hb_FileExists(), ::AuthPlain()
      simplification).
    % BUILDUSERPASSSTRING() rewritten in Harbour. It's a very
      simple function.

Harbour switch handling spec
============================
This spec goes for CLIPPERCMD, HARBOURCMD, Harbour
compiler and #pragma directives in the source code.
The command line always overrides the envvar.
Note that some switches are not accepted in envvar,
some others in #pragmas.
First the parser should start to step through
all the tokens in the string separated by
whitespace. (or just walk through all argv[])
1.) If the token begins with "-", it
should be treated as a new style switch.
One or more switch characters can follow
this. The "-" sign inside the token
will turn off the switch.
If the switch has an argument all the following
characters are treated as part of the argument.
The "/" sign has no special meaning here.
-wn ( W N )
-w-n ( !W N )
-wi/harbour/include/ ( W I=/harbour/include/ )
-wi/harbour/include/n ( W I=/harbour/include/n )
-wes0n ( W ES=0 N )
-wen ( W [invalid switch: e] N )
-wesn ( W ES=default(0) N )
-wses ( W S ES=default(0) )
-wess ( W ES=default(0) S )
- ( [invalid switch] )
-w-n-p ( !W !N P )
-w-n-p- ( !W !N !P )
-w- -w -w- ( finally: !W )
2.) If the token begins with "/", it
should be treated as a compatibility style switch.
The parser scans the token for the next "/" sign or EOS
and treats the resulting string as one switch.
This means that a switch with an argument containing
"/" sign has some limitations. This may be solved by
allowing the usage of quote characters. This is mostly
a problem on systems which use "/" as path separator.
The "-" sign has no special meaning here, it can't be
used to disable a switch.
/w/n ( W N )
/wo/n ( [invalid switch: wo] N )
/ihello/world/ ( I=hello [invalid switch: world] [invalid switch: /] )
/i"hello/world/"/w ( I=hello/world/ W )
/ihello\world\ ( I=hello\world\ )
3.) If the token begins with anything else it should
be skipped.
The Harbour switches are always case insensitive.
In the Harbour commandline the two style can be used together:
harbour -wnes2 /gc0/q0 -iC:\hello
Exceptions:
- Handlig of the /CREDIT undocumented switch
on Harbour command line is unusual, check the current code
for this.
- The CLIPPER, HARBOUR and Harbour application
command line parsing is a different beast,
see cmdarg.c for a NOTE.
Just some examples for the various accepted forms:
//F20 == /F20 == F20 == F:20 == F20X
//TMPPATH:C:\hello
F20//TMPPATH:/temp///F:30000000 NOIDLE
F0NOIDLEX10
SQUAWKNOIDLE
"//" should always be used on the command line.
