Hello Yuri, this is a known issue.

This used to be defined as
#ifdef __cplusplus
#  define ANYARG ...
#else
#  define ANYARG
#endif

We removed it because gcc 12 do not like it, and that definition is not particularly
useful.

So you can replace this by

typedef GEN (*PFGEN)();

if you like, but recent gcc 12 will issue warning.
In PARI we changed EVAL_f to cast the pointer to the right prototype
before calling it.

Cheers,
Bill.
