[cvs-nhc98] patch applied (hat): Hat: add error-case hooks in archive file.

Mon Mar 12 08:17:58 PST 2001 malcolm * Hat: add error-case hooks in archive file. When terminating the program with an error, plant an error message and expression-root at the beginning of the archive file. This applies to pattern-match failures and black-holes at the moment. Interrupts are still to come. M ./src/old/runtime/browsercomms.c -2 +29 M ./src/old/runtime/io.c +5
