#2766 Function Prototype

[Kawai]

I tried to compile FreeRTOS Demo Program, but SDCC reports an error message at xTaskCreate()funcition-call in the flush.c.
So, I made test program to look into the cause of the error and found an curious behavior.

Though I checked it on SDCC 3.5.0 and SDCC3.7.1 , both compiler says same error msg.

//***Source-A
const char * const pMsg = "Hello World!\n";
void ss(const char* const * pDisp);
void main(void)
{
 ss((const char * const *)&pMsg);
}
void ss(const char* const * pDisp)
{
}

$ sdcc test.c
test.c:7: error 78: incompatible types // <=== Error occured !!! (What on earth is the matter?)
from type 'const-char generic const code fixed'
to type 'const-char generic const unknown fixed'
test.c:12: warning 85: in function ss unreferenced function argument : 'pDisp'

On the other hand.....

//***Source-B
const char * const pMsg = "Hello World!\n";
void ss(const char* const * pDisp)
{
}
void main(void)
{
  ss((const char * const *)&pMsg);
}

$ sdcc test.c
test.c:5: warning 85: in function ss unreferenced function argument : 'pDisp'
(There are no error messages)

Looks like I just fixed this one today in [r13388] while fixing bug [#2629].
