[Chicken-hackers] [PATCH 0/1] Fix spurious array bounds warnings on OpenBSD

[Evan Hanson]

Hi folks,

Here's a fix for #1107 that avoids futzing with feature macros or
standards flags while still dispelling the warnings on OpenBSD. It just
bumps the size of the C_block_item struct's data field from the smallest
possible value (1) to the largest possible value (INT_MAX). This doesn't
actually change CHICKEN's behaviour since that value is unused -- it's
just a hack to declare what is really a flexible array member in C99 --
but it will increase the array size that the compiler uses for bounds
analysis and as a result it will stop the unnecessary warnings.

I propose this as a solution rather than introducing "-std=c99" or some
other such flag since CHICKEN doesn't currently require a C99 compiler
and I'd prefer not to give up our C89 compatibility.

Let me know what you think,

Evan
