Hi!

According to MySQL coding guidelines:
https://dev.mysql.com/doc/internals/en/additional-suggestions.html

<quot>
* In C code, use TRUE and FALSE rather than 1/0

* In C++ code, it is OK to use true and false (do not use 1/0). You can use C++
  bool/true/false when calling C functions (values will be safely promoted to
  my_bool).
</quot>

I'm aware of only one more or less good reason for not using true/false in C++:
it's easier to convert it to C code. But that's rare: we mostly convert in the
opposite direction.

Also C99 now supports true/false, e.g. see nice description:

Regards,
Sergey
