I know the cause of this.  SCO has a buggy compiler in several (many?)
releases, and one of our macros is too large for the compiler.  There is
a DISABLE_COMPLEX_MACRO define that turns off an inline macro for sco.

In 7.0.X, it seems the include file using the macro is also called by
ecpg, and because ecpg does not include the C file that defines the
non-inline version of the macro, it fails.  At least that is my guess.

I am testing the current tree now, but one solution is to remove the 
DISABLE_COMPLEX_MACRO defined from ./include/port/sco.h.

Unfortunately, I can't reproduce the problem in the current source tree.
