Let's see:
$ grep -r RETSIGTYPE lib
lib/flinternal.h:typedef RETSIGTYPE(*FL_OSSIG_HANDLER) (int);
lib/signal.c:static RETSIGTYPE
lib/signal.c:#ifndef RETSIGTYPE_IS_VOID
lib/config.h.in:#undef RETSIGTYPE
lib/config.h.in:#undef RETSIGTYPE_IS_VOID

$ grep RETSIGTYPE build/lib/config.h
#define RETSIGTYPE void
#define RETSIGTYPE_IS_VOID 1

config.h is a file generated by the configure script from config.h.in 
which, in turn, is generated by autoconf from configure.ac. Given 
that you don't have the autotools at your disposal, I'm attaching 
both so that you can create your own config.h using config.h.in as a 
template.

Here, on linux, 'man signal' gives me this signature, confirming that 
RETSIGTYPE should be 'void' on this platform.
       #include <signal.h>
       typedef void (*sighandler_t)(int);

Regards,
Angus
