Dear friend: I forward the following query from our system administrator:

Will your product run if we upgrade our SUN machine from SunOS 4.1.2
to Solaris 2.1? In other words, SunOS 4.1.2 and Solaris 2.1 are
not binary compatible. However, Solaris 2.1 has a 4.1.3 compatibility
mode which is sufficient for many products. SUN suggests, however,
that we contact each vendor and ask if their product will continue to
run in compatibility mode or not.

Hence this question. Will GAP run in compatiblity mode under
Solaris 2.1?

Thanks for your help.
Yours, Mike.
