Leading zero is used as an identifier for octal numbers. "017" is decimal 
8+7=15. Octal numbers only have digits from 0 to 7 so thats why 07 works but
08 + 09 doesn't - they are no valid octal numbers.

It should be possible to change the regexp for GNU compilers in compile.sl
to eat up the leading zero to fix this problem - or the internal function
"compile_parse_errors_dir" should do that on any line or column number. 
I doubt any compile prints anything else than decimal numbers.
