Current code for AC_CHECK_DECL uses
#ifndef $1
char *p = (char *) $1;
#endif
Thomas suggests
<thomas>

because some compilers won't error on a char* - a struct is better,
and it's complex to make it less likely that it matches an existing
struct.

First of all, I don't get what this #ifndef is doing here in
Autoconf, it does not test what I need, so AFAIC I'd vote for
char *p = (char *) $1;
or maybe
#undef $1
char *p = (char *) $1;
A difference I see between Thomas' approach and Autoconf's is that
Autoconf does not try to force the symbol whose declaration is being
checked to be a function. AC_CHECK_DECL can them be used for errno,
sys_siglist and others.
In this case, Thomas, do you think we still need all the zowie stuff?
