[PATCH] waveout: fix compilation warning / error

[Johannes W. <ja...@mo...>]

For me this fixes:
waveout.c:283: warning: implicit declaration of function 'snprintf'

But for the reporter, the warning is an error (possibly newer version of
toolchain?):
waveout.c:283:3: error: implicit declaration of function 'snprintf'

The <stdio.h> header is included after the <windows.h> header, as
suggested e.g. here:
http://en.wikibooks.org/wiki/Windows_Programming/windows.h
