Lemme get this straight.  Your compiler complained about:

TDS_PBCB colclause = { clause_buffer, sizeof(clause_buffer) };

even though both values are known at compile time (never mind that it's an
ANSI standard construction)?  I find this hard to believe, not because I
don't trust you, but because I've been initializing structures that way
since before Bill Gates dropped out of Harvard.  It's explained and
illustrated in section 6.3 of "The C Programming Language", copyright 1988.


Does this work:

enum {CLAUSE_BUFFER_SIZE = 4096};
char clause_buffer[CLAUSE_BUFFER_SIZE] = {0};
TDS_PBCB colclause = { clause_buffer, CLAUSE_BUFFER_SIZE };

Does this:

#define CLAUSE_BUFFER_SIZE 4096
char clause_buffer[CLAUSE_BUFFER_SIZE] = {0};
TDS_PBCB colclause = { clause_buffer, CLAUSE_BUFFER_SIZE };

Section 2.4 of the same book, wherein initialization of variables is
described, says initialization of automatic variables may be done with "any
expression".  I think someone should mention this to Sun?  I could send them
a copy.
