Can't build gdb 5.0 for sparc64-sun-solaris2.7

[Kevin Neel]

I would like to use gdb on programs running in 64 bit mode (v9 mode) on
Solaris 2.7. Looking at the config scripts, I assume that building with
'../gdb-5.0/configure sparc64-sun-solaris2.7' (in an empty sister directory)
should work. But I get compile errors when doing so; some register macros
that are #defined for sparc are #undefined for sparc64, but still used.

I have tried buillding after configuring with CC='cc -xarch=v9' [for Sun's
64 bit compiler] and with CC='gcc-2.95' [in 32 bit mode]. Same problem
arises in each. I am building on an Ultrasparc-II system running Solaris
2.7.

E.g., the output from gcc:

Any ideas?
