- update to 2020.06.01:
* SVG text adjustments; GCC-10 conformance.
* Commas protected by brackets; zero-repetition "for" loop bugfix
under bison.
* Fix of environment variable scope, arc attribute; improved error
messages; generalized macro definition.
* Corrected typos, copyright notices, version number, string treatment.
* Bugfix for buffer overflow with extreme arguments of wfloat().
* This is a major clone of the previous distribution, which
contained compilable C code together with the original pascal
source. The pascal was translated to C code using p2c,
which was included, and parsing was automated by a custom
compiler-compiler which was also provided. The current
package includes C source only with parsing automated using
GNU bison. The original lexical analyser has been kept. To
avoid introducing bugs, the C code has been changed only to
accommodate bison; some p2c idiosyncrasies remain. The result
is functionally identical to the previous version for correct
input.
