which gcc? (cross dist: egcs-2.91.60, macppc dist: egcs-2.91.66)

[Tad Hunt <tad%entrisphere.com@localhost>]

I downloaded and installed the cross compiler package for powerpc
for NetBSD-1.5 i386 (cross-powerpc-netbsd-1.3.0.0.tgz) which claims
to be:

        egcs-2.91.60 19981201 (egcs-1.1.1 release)

I've been compiling the kernel and user stuff quite successfully
with this cross compiler.

I just noticed that the native NetBSD-1.5-macppc version of the
compiler is:

        egcs-2.91.66 19990314 (egcs-1.1.2 release)

Am I going to run into problems using the cross compiler package
egcs-2.91.60? Should I attempt to build the cross compiler myself
to match versions with the macppc port?

What might be the "officially blessed" version (if any!) of gcc to
depend on for the powerpc ports?

Thanks!
