Details:

Since gperf 3.1, applications such as "libcap" fail to compile. The reason is
that the generated code uses "size_t" without including stddef.h. Furthermore,
the prototype is not consistent with the actual function definition.

This is likely a regression introduced with v3.0.4-47-gd519d1a ("Change the
'len' parameter type to 'size_t'.").

This was previously reported in
https://lists.nongnu.org/archive/html/bug-gperf/2017-01/msg00004.html

What about reverting this change? If applications actually need to handle
"size_t" data, what about adding a new option for it (but default to the old
behavior)?
