In kernel space we use USE_SEQ_MACROS in:
sound/oss/mpu401.c
sound/oss/midi_synth.c
so we can replace
#if (!defined(__KERNEL__) && !defined(KERNEL) && !defined(INKERNEL) && !defined(_KERNEL)) || defined(USE_SEQ_MACROS)
with
#ifdef USE_SEQ_MACROS
Then this will break user-space apps.  They don't define
USE_SEQ_MACROS always.
If userspace apps are coming through sys/soundcard.h we can define
USE_SEQ_MACROS in it 
OR 
define USE_SEQ_MACROS in linux/soundcard.h for userspace 
OR 
need to redefine better #ifdef
