Thanks a lot for your fast reply.

'gcc' does not seem to cause any problems. Unfortunately for our user in
Zimbabwe, getting GNU C would be a major undertaking.

The problems you had in 'system.c' were probably caused by a conflict
between the declaration of 'signal' in 'system.c' and the Solaris include
files. In this case just building with
'make COPTS=-DSYS_HAS_SIGNAL_PROTO' should also solve it.
Could you check, whether this is true?

Martin.
