Force blocking y comm doesn't work anymore

channel/Makefile

Lines 47 to 55 in dcc9c3b

	# for uiuj (various versions)
	postpro/tke/uiuj_largesmall: flags += -DforceblockingY
	postpro/tke/uiuj_spectra: flags += -DforceblockingY
	# for runtime statistics
	runtime: flags += -Druntimestats
	postpro/conditional/Velocity_cut: flags += -DforceblockingY
	postpro/conditional/zero_crossings: flags += -DforceblockingY

The -DforceblockingY flag does not produce the desired effect anymore. This flag is used to disable the non-blocking communication when compiling some postprocessing routines, regardless of whether the non blocking communication is enabled in header.h. See also the following lines:

channel/header.h

Lines 12 to 14 in dcc9c3b

	#ifndef forceblockingY
	#define nonblockingY
	#endif

The problem might as well be with the C preprocessor.
