After a bit more mangling of code I've managed to this Small C compiler to output code. I have not idea if it's correct and I need to still do a conversion from the CRASMB or XASM680X assemblers. I have documentation for the CRASMB assembler so I hope to be able to translate this from CRASMB to asl (the assembler I like to use). At the moment I have the Small C compiler taking some sample code and output it. Unfortunately that code really isn't for this compiler so I need to use one of the examples in the Flex LIB5* disks I have. Good news I I do have Flex emulators and a Flex machine (PT69-5A) working so I should be able to start testing there soon.
