objc - missing current_function_returns_abnormally global variable initialization?

[Marcin Dalecki <martin at dalecki dot de>]

I have been looking closer at the following C front-end global  
variables:

  current_function_returns_value
  current_function_returns_null
  current_function_returns_abnormally

Which are declared in c-decl.c. They are basically used as a way to  
communicate with c-typeck.c.
All have to be initialized there to some default values.

Analogously for objc it appears that the same initialization have to  
be done
in objc-act.c. However as it is the initialization of  
current_function_returns_abnormaly
seems to be missing. If the reinitialization isn't necessary at all  
it could be deleted.
However if it's really missing - it will result in at least  
inconsistent error reporting for objc.

The attached patch basically just illustrates the places where the  
issue arias in the most precise way possible. It's changing in  
addition the data types used to a proper bool, since this is
reflecting the usage of those variables more properly.

Could someone with are more thorough understanding of the interaction  
between the c and objc parser take a closer look at this? Thanks.
