2014-05-12opl: Handle negative time division values.Simon Howard
A negative time division file indicates the MIDI file uses SMPTE time rather than the normal time system. This is not supported yet, but for the time being, return a sensible time division value that doesn't cause the sound to stutter and the game to become unplayable. This fixes #352, although the affected MIDIs do not yet play properly.
2014-05-05Clean up file headers.Simon Howard
This change rewrites and simplifies the copyright headers at the top of all source files: * Remove "Emacs style mode select" line; this line was included in the headers for the originally released source files and appears to be to set the file type for old versions of Emacs. I'm not sure entirely why it was required but I don't think it is any more. * Remove "You should have received a copy of..." text from copyright header. This refers to the old 59 Temple Place address where the FSF headquarters used to be located and is no longer correct. Rather than change to the new address, just remove the paragraph as it is superfluous anyway. This fixes #311. * Remove ---- separator lines so that the file headers are barer and more simplified.
2014-04-10midifile: Fix portability issue with malloc(0).Simon Howard
In the C standards, malloc(0) may return NULL without indicating a failure to allocate. As values read from the MIDI file may be arbitrary, add one to the allocated length so that we always allocated a positive value. This fixes #165 (thanks nmain).

2010-09-10Post-merge fixes: Created project for OPL library. Fixed OPL library toJames Haley
not use GNU C-isms such as inline keyword, declaration/statement mixing, and strange calling convention syntax for import function pointers. Fixed critical buffer overflow in M_BindChatControls - should be back-merged immediately. Added autogenerated directories *back* to ignore list.
