I recently installed SL5.2, which generally works well, but gcc is unable
 to
report the symbols that it is having difficulty compiling...

For example, if I compile the following program:

int main() {
  double d = 1.5;
  e = d + 2;
}

I get the following:

$ g++ junk.cc
junk.cc: In function â:
junk.cc:3: error: â was not declared in this scope

As far as I can tell, everything else about g++ seems to be working.

Here is my system info:
