[SPARCbook] Need sparcbook2 solaris 1.0.1 gcc later than 2.1

[BSD Bob]

Anyone know where I might find a precompiled solaris 1 (or sunos 4.x)
gcc 2.5.8 or 2.7.2.3?  I need to update the compiler on my SparcBook2
(version gcc 2.1) which has some bugs compiling things like GnuPlot.

Any pointers to such a compile are appreciated.  Sunsite and such only
have compiles for Solaris 2.5 and later.

Thanks

Bob
