| // coff.h - Common Object File Format (COFF) support |
| // |
| // This file was developed for the avra assembler in order to produce COFF output files |
| // for use with the Atmel AVR Studio. The Lean C Compiler (LCC) debugging stabs |
| // output was used as input to the assembler. |
| // |
| // This software has absolutely no warrantee! The money you paid for this will be |
| // promptly refunded if not fully satisfied. |
| // |
| // Beta release 1/20/2000 by Bob Harris |
| // |
| // This software has not been fully tested and probably has a few software deficiencies. |
| // Some software support may be possible by sending a problem description report to |
| // rth@mclean.sparta.com |
