SQL0312 when compiling with v7.3 CRTSQLRPGI

I have found something that may be a bug in 7.3, but I am unsure if it has
been PTFd yet as I can't find a PTF for it. I understand that my Google Fu
for IBM PTF's is weak at best. Here is the issue:

I have a program that compiles fine on 7.2, but fails on 7.3. I can make it
compile on 7.3, but the change I have to make seems to indicate that the
precompiler has lost some flexibility. I have a couple host variables that
are defined with like(). The target of the like is a subfield of a data
structure defined with a likerec(). In 7.2 the order of these definitions
does not seem to matter, in 7.3, it does. If the fields with like() are
defined first in 7.3, I get an SQL0312, in 7.2 it compiles correctly. If
the data structure is defined first on 7.3, it compiles correctly. I didn't
check this scenario on 7.2 because I can't imagine it failing, and I am
sure that I have done that.

Does anyone know of a PTF that might fix this problem? or should I have our
admins report this to IBM? Not that 7.3 is a high priority for correcting
things like this any more, or maybe the change was intentional, but I can't
find any documentation confirming this hypothesis either.
