I have an application using Ingres (the University Ingres, not RTI Ingres)
under IBM AIS 4.2 on an RT.  I was told (by my colleagues) that the Ingres
code (together with the source) was from Brown University and that they
don't know whom to contact there.

Now I'd like to upgrade my machine to IBM AOS 4.3.  I tried to compile
the source on another (upgraded) RT.  With "hc", there are many error/warning
messages so I switched to "pcc".  After a few minor changes (to the source)
it compiled through, but the new binary doesn't run well (it runs, but I
have found one major problem - the code is not usable).

Yes, I tried to compile my application under AOS 4.3 with the original Ingres
binary code.  Everything seems all right except the following message:

ld:/lib/libc.a: warning: Old and new floating point linkages encountered
 (symbols FPaGET0 and FPGLUE present); performance degradation may occur.

I assume that it's ok to just use the old Ingres code (how serious may this
"performance degradation" problem be if there's indeed a problem?), but does
anyone have the source that will compile and run well under AOS 4.3 on
an RT?

Also is there an RT version of RTI Ingres, either under UNIX or under AIX?
