 I have rechecked. Actually NO_OUTPUT_SYNC is defined only by handmade
config.h files for DOS, VMS and Amiga. EMX uses configure script, so
NO_OUTPUT_SYNC will not be defined.
However, indeed, there is rational seed in what you say. Since this code
actually goes to generic part, it will be useful to be able to disable this
code, just in case.
 Please take the updated patch. I have verified it to build by supplying
CPPFLAGS=-DNO_OUTPUT_SYNC to configure.
