I have the following program which does not generate any error messages
from the compiler nor does it seem to output any assembly code for
this particular case:

extern void foo();

...


void foo()
{
 ...
 ...
 ...

}


In a later part of the program in some function I call foo:

	foo;

The parenthesis are missing and the compiler does not point this
error out.  It does not seem to generate any assembly code for this 
call to the function (procedure) "foo".

I am compiling the program on a Sun-3 running Sun-OS 4.X and using the 
cc compiler.  

I want to know whether this error should be pointed out by the compiler?

If the answer is no,  what is the reason?

It took me a day or so to spot this error when I tried to set a breakpoint
at this statement in dbxtool which automatically set the breakpoint
at the statement following this one. 

Could you please email me any replies and I will summarize if there is 
interest.
