Does CCS C compiler support functional prototypes?

[klanglais]

Code:
void lcd_cmd( char cmd ); // subroutine for lcd commands
void Delay( unsigned int delay_count );

/****************************************************************************/
/***** LCD SUBROUTINE *****/

void Init_LCD( void ) // initialize LCD display
{
// 15mS delay after Vdd reaches nnVdc before proceeding with LCD initialization
// not always required and is based on system Vdd rise rate
Delay(Delay_15mS_Cnt); // 15ms delay


Error:

I am using CCS C version 4.071 with MPLAB 8.00.
Thanks

The compiler did not issue any error about the functional prototype, so I think that is OK. What the error said was that the function was not defined. The functional prototype does not define a function. It only declares a function. You still have to supply the function code itself. That is the "definition" that is lacking.
