The typ2yam Typhoon->Yamaha converter is very sparsely tested In fact I have only compiled and run it on one configuration (architecture/OS/compiler): SPARC/UNIX/gcc If you succeed in compiling and running typ2yam on any other configuration, I would appreciate if you report your success to me (stein.kulseth@fou.telenor.no), and I will add this to the above list If you encounter problems in compiling or running this code then check the bugfix list below to see if you have the most recently updated version. If you do, then I would appreciate if you report your problems to me (stein.kulseth@fou.telenor.no) List of bugs found-and-fixed : 96/02/19 Found a "slip of the pen": if (strcmp(buf, "DWVW") != 0) Corrected: if (strncmp(buf, "DWVW", 4) != 0)
