Summary: enum leading to warning 185

Initial Comment:
The following code:

enum {
  ENUM0,
  ENUM1
};

enum {
  ENUM0a = 0
};

volatile unsigned char a;

void main(void) {
  if (a == ENUM0);  // only this line triggers 

warning 185
  if (a == ENUM1);
  if (a == ENUM0a);
}

leads to:
c:\tmp>sdcc bug.c
bug.c:13: warning 185: comparison of 'signed char' with 'unsigned char' requires promotion to int

c:\tmp>sdcc --version
