diff lshlib.h @ 648:4b79043f90ba

hack lshlib into happiness with mingw

_locking() for file locking; hardcode pagesize as 64k; use
lseek()/read()-write()/lseek() and buffers to emulate mmap().

I haven't actually tested all this lshlib functionality, but with this
change I can build an audioDB.dll which works well enough to be linked
into a binary which seems to work under Wine.
