We have clients using our AIX 4.3.3 xlf 7.1.0 compiled programs. In order to
install a PTF to fix a compiler problem, we may have to upgrade to xlf 7.1.1.
We have been sending libxlf90.a with our fortran executables.

After going to 7.1.1, will we have to redistribute the new libxlf90.a to our clients
when we send newly compiled programs? What about previously compiled 7.1.0 programs?
will they work with the new libraries? Will we have a compatibility problem?

thank you.

Probably.

Yes. At least, they better.

You should not, AFAIK. The idea is that current runtime
levels support older programs. You will likely want to
test the existing product levels with the new runtime,
just to be safe, and then build/test your new product
level again. Ideally, though, only those things you
have to change/enhance/fix will need to be installed
by the customer. I.e. older + newer components of your
application should work together.
