Ray Chason 5eaa162c82 Define and use PRINTF_F_PTR ...

GCCs older than 3.1 understand __attribute__(printf(...)), but only
with functions; it doesn't work with function pointers. This change
uses PRINTF_F_PTR to remove the attribute from two function pointers.

This change establishes GCC 3.0 as the minimum version to build
NetHack. Older versions have trouble with the variadic macros and
variable declarations in mid-block.
