Subject: [PATCH] Fix "assignment from incompatible pointer type"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I encountered this warning from gcc 7.3.0 building on Ubuntu:

dbdimp.c: In function ‘mysql_st_prepare’:
dbdimp.c:3207:24: warning: assignment from incompatible pointer type [-Wincompatible-pointer-types]
           bind->is_null=      (_Bool*) &(fbind->is_null);

The "MYSQL_BIND" field "is_null" is of type "my_bool", not "_Bool".

The type "my_bool" is (usually) type-defined to be of a "char" type.

Regardless, the "imp_sth_phb_t" field "is_null" is of type "char".

This commit removes the cast, which means that if we later discover
that "my_bool" is defined to be of a type incompatible with the
"imp_sth_phb_t" field "is_null", it will break at compile-time.
