My previous patch on this broke "make check" in ecpg,
so ignore that. Your comment that it's a bug in Informix-mode
made me look around more. Find the attached patch I came up with.
Now my previous test code works and produces similar C code
as without "-C INFORMIX". Can it be this simple?
Can you see anything wrong with this approach?
