For "simple" BLISS programs, it isn't hard.  However, once you start using 
BLISS' preprocessor (which is actually part of the language), it goes 
downhill really fast.  Plus, features like LINKAGEs for interoperability 
with Macro-32 and C programs (that use the linkage pragma) also mess things 
up.  Excessive use of BLISS' expression features also resulted in C that was 
going to be difficult to maintain going forward.

VMS engineering looked at BLISS to C converters many times (including 
writing our own using the actual BLISS frontend).  Worked for some, but fell 
short when trying to convert more complicated BLISS code (like RMS or even 
the BLISS frontend itself).
