Ok, I downgraded that and another check to warnings (and tightened
couple of other checks, see latest breakcond.c change).

What kind of a syntax/prefix you'd thought for ASCII and binary values?
Should they be allowed also for specifying addresses, or is it enough
that addresses can be specified only as decimal or hexadecimal?
Btw. Decimal is currently the default number format in conditional
breakpoints, hexadecimal values need to have the '$' prefix as you
