Compilation fails (generating function prototypes?)

[bobsuname]

Here's the last part of the verbose output (same problem occurs if compiling for UNO):

Not much of a clue. I found a bad prototype in a library header file that isn't used by the sketch I was trying to compile, but fixing it didn't change the failure. Ideas?

Could you paste a full (but preferably reduced as much as possible) sketch that shows the problem, including any libraries needed?

[bobsuname]

I suspect the problem is not in the particular libraries used (unless it's the Serial library). I get the same error when I try to compile the following:

// test operations with ints and unsigned longs

unsigned long time, result;
int delta;

void setup()
{
  time = 17000000UL;
  delta = 222;
  result = 0;
  
  Serial.begin(9600);
  while (!Serial);
  Serial.println("Hit return to start");
  while(Serial.read() < 0);
  result = time + delta;
  printit(" plus ");
  result = time - delta;
  printit(" minus ");
  delta = -delta;
  result = time + delta;
  printit(" plus ");
  result = time - delta;
  printit(" minus ");
}

void printit(char *str)
{

  Serial.print(result);
  Serial.print(" = ");
  Serial.print(time);
  Serial.print(str);
  Serial.println(delta);
  return;
}

void loop()
{
  ; // do nothing
}

Here's the entire verbose output from the compilation

It gets better: the following sketch fails in the same way (same error code):

void setup() {
// put your setup code here, to run once:

}

void loop() {
// put your main code here, to run repeatedly:

}
I tried reinstalling the IDE (both 1.8.2 and 1.8.3) to no avail.

I tried recreating the ../AppData/Local/Arduino15 directory, and this seems to have worked. i'm not sure what got messed up therein.
