I am compiling a modified version of minix-st 1.5.10 with gcc. To circumvent
the gas/mot assembler syntax problem i wrote a tool called cv68 which converts
motorola syntax to gas syntax. The tool is written using flex which was ported
to minix times ago. Since i used flex and not yacc everything is quite simple-
minded. Some very special addressing mode (absolute address with short/long
specification - used in tools/boot.s) confuses it, but every other asm file
coming with 1.5.10 can be converted and compiled by gas correctly.

As far as i know R.Orth (ro@thp.uni-koeln.de) is preparing a new gcc kit
which will contain my cv68 tool. However, i can post it now if there's enough
interest.
