Conditionalize 'warning: non-ANSI function ...'
Sparse unconditionally issues warnings about non-ANSI function
declarations & definitions.
However, some environments have large amounts of legacy headers
that are pre-ANSI, and can't easily be changed. These generate
a lot of useless warnings.
Fix this by using the options flags -Wstrict-prototypes &
-Wold-style-definition to conditionalize these warnings.
