I've never had a problem with using a 4.1.3 binary
on earlier 4.1.X. Looking
at my gcc distribution. I've put a distribution at
http://setiathome.ssl.berkeley.edu/~korpela/gcc_sunos_4_1.tar.gz
It extracts to a subdirectory (gnu). The executable directory is
gnu/H-sparc-sun-sunos4.1/bin
The only issue is with some dynamically linked libraries (linked
against shared libraries that don't exist....
Some symlinks usually fix that.
