layout of modules. To use this new compiler, you need a matching stdlib,
i.e., revision 1042 or newer.

which is needed when compiling prelude itself (whas automagically
before) and handy when debugging small programs.

out after optimizations if -check c is not specified.

Mac file prf_info.mac rewritten.
Outdated table entries removed and functionality re-implemented.
Code generation for prfs re-implemented.
Some features added to string library.

new columns for CF refactoring.

Syntax tree sanity checks activated by default in developer version
to indicate problems at an early stage.

in traversal mechanism. These checks are intended as an intermediate
solution until -d treecheck works.

using colons to separate phase, subphase and cycle phase.

 + Improved compile time output
 + More intuitive break option
 + New verbosity layer to track function-based optimisations
 + Tree-like organisation of phase/subphase/cyclephase names:
     Subphases in different phases may have same name.

an executable.
Extended the phase mechanism such that the entire compilation process
is full generated from macro definitions.
Beautified the way optimisation and type statistics are printed.
Prepared sac2c for multiple compilation processes, e.g. renamed
phase_info.mac to phase_sac2c.mac.

compiler module support/str.
Extended refactoring mechanism by additional condition.

Usage and option handling is generated from phase_info.mac
phase_info.mac is brought in-sync with phase calls, which are
not yet generated.
phase_info.mac now reflects the entire compilation process
including multiple optimisation cycles and function-based
optimisations.
Many compiler modules required modification to stream-line 
compiler phases in a way that allows the complete generation
of phase drivers in the near future.

phase/subphase mechanism. All phase drivers are concentrated
in a new file phase_drivers.[ch]. Prototype declarations and
the compiler driver are automatically generated from phase_info.mac.
Code generation, C compiler invocation and library creation are
reorganised to use the phase/subphase mechanism.

Setup is no longer done in a standard phase, but before the
phase mechanism starts.
Pre- and post option checks are integrated into the normal
command line analysis.
ScanParse is reorganised into 3 subphases and the handling
of cpp arguments and the cpp call is re-implemented without
static buffering.
To keep the phase numbering unaffected, I introduced a new 
phase 'preprocess' distinguished from scanparse.
Weird initialisations in DupTree and check_lib are replaced
by more appropriate code.

Streamlined initialisation of memcheck.
Made handling of -d memcheck option in accordance
with compiler infrastructure guidelines.

Explicit initialisation is now entirely removed to avoid
similar problems in the future.
