+ 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.

other than for building, e.g. cleaning or refactoring, have been
moved into individual makefiles already.

Added new makefile feature to add private settings.

which was not able to handle nested setwls.

essentials_h, respectively. This is to avoid clashes with other
meanings of the term 'core'.

is only supported by newest versions of gmake.

bottom types, as all other type errors. Therefore, conditionals
containing a dispatch error in one branch are not rejected if
the other branch typechecks fine.

YY_NO_UNPUT is one too much. I have kept the define, as that is more
portable between lex/flex/bison.

falsely fail.

new functions from str.c and memory.c rather than the old ones 
from internal_lib.

However, internal_lib itself has not yet been removed from system.

new compiler module support/math_utils.

compiler module support/system.

into dedicated compiler modules support/str_buffer and support/ptr_buffer.

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

Moved cachet from maketools into ctest in tools.
Added correct modelling of the subtle dependence between libsac2c
and libsacprelude via fingerprints of the ast to the makefile
mechanism.
Moved all configure-related files to a new top-level subdirectory
setup. The configure script in root now is a simple shell script
that invokes the real configure in setup.
Moved all sac2crc-related files from include to setup.
The configure-generated sac2crc file now resides in the project root
directory and the compiler sources are adjusted accordingly to look
after sac2crc in the right places.
The various source files of sac2crc are tidied up and all machine
specific targets are removed.
The LICENSE file is updated and moved to the project root directory.
The html documentation of the ast is now automatically created and 
stored in the new subdirectory src/html.

bin and lib. The subproject makes only remove their specific targets.

Fixed nasty bug in dependency tracking mechanism.

Bug fixed in source directory compilation.
