+ added support for -gd[.<destExt>] switch.
When used Harbour compiler generates also .d file with dependencies
list in the form like for make systems:
<destFile>: <sourceFiles,...>
optional .<destExt> parameter value can be used to replace default
extension in <destFile>.
Now users can generate .d files without additional overhead in the
same pass as normal compilation by simple adding -gd[.<destExt>]
switch to compilation command instead of executing harbour compiler
second time with -sm switch.
