Of course… stupid me :-)

Well, I didn't change them because it doesn't match the protos which
are (copy-paste) :

  int tgetent(char *bp, const char *name);
  int tgetflag(char *id);
  int tgetnum(char *id);
  char *tgetstr(char *id, char **area);
  char *tgoto(const char *cap, int col, int row);
  int tputs(const char *str, int affcnt, int (*putc)(int));

That's from the man for Linux and FreeBSD and from the source for AIX.

Thanks!

Yes, it's conflicting with the available header.

I haven't spent much time checking who includes who, but it seems that
prototypes.h is included by zsh,mdh which also includes config.h
beforehand but neither defines USES_TERMCAP_H nor USES_TERM_H (which
is done, as expected, by termcap.c).
