Description Ian Romanick 2001-10-19 17:12:47 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.5) Gecko/20011012

Description of problem:
cproto generates prototypes of the form:

extern const char * foo( void ) = {0};

for functions of the form

const char * foo( void )
{
    return( NULL );
}

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.Create a file called x.c with the single line "const char
*foo(void){return (void*)0;}"
2.Run "cproto x.c"

	

Actual Results:  cproto produced the output:

/* x.c */
const char *foo(void) = {0};


Expected Results:  I expected cproto to produce:

/* x.c */
const char *foo(void);

This doesn't happen for a current version of cproto.
