In our compiler we have
	#pragma equate foo_bar foo-bar
which works like a #define to the parser (ie. the parser converts foo_bar
into foo-bar for the code-generator and linker). We also have
	#pragma alias foo_bar foo-bar
so that the object named by foo_bar is given another name, which can be
used by a module written in a different language (or by the C library, to
avoid conflicts with user defined routines).
