* Turned the msg() and debug() functions into macros, since they
...
turned out to be a huge performance bottleneck (the text to printed
would always be evaluated, even when it was above the verbosity
level). This reduces fix-ng execution time by over 50%.
gprof(1) is very useful. :-)

* Work around problems with the ATerm library.
...
The ATerm library doesn't search the heap for pointers to ATerms
when garbage collecting. As a result, C++ containers such as
`map<ATerm, ATerm>' will cause pointer to be hidden from the garbage
collector, causing crashes. Instead, we now use ATermTables.

...
semicolons instead of comma's. Final semicolon in the set is optional.

* Use SGparseString() instead of SGparseFile() because the latter is
...
buggy. It fails to clear an internal variable (SG_textIndex)
between invocations, so it can be called only once during a program
execution.

removed, paths are absolutised relative to the path containing the
expression we just parsed, and integer literals are converted to
actual integers.

friends to do the parsing. The parse table is embedded in the Fix
