Why? Can't you just put it into a header file that is processed by ecpg
to create a C header and use "-c" for this? Okay, this does include the
ecpg headers also, but if that's the problem we could add an option
easily.
How about an option "parsing header file"?

Would it be okay to do this:
Write a *.pgh file, that is SQL-INCLUDE-ed in embedded sql files. For C
you'd call "ecpg -h" on that file, making ecpg produce a .h file, that
can be included by your C code.
Hmm, I think I'm going to implement that immediately. :-)
