I'm still waiting for IT to get me the 8.2 source so I can try that
version, but in the meantime: I'm seeing this error in Solaris 10 (sparc)
with 8.1.1. I built gdb configured like this:

/path/to/src/configure \
--prefix=/install/path \
--enable-plugins \
--enable-tui \
--with-python=yes \
--disable-largefile \
--without-system-readline \
--enable-64-bit-bfd \
--with-expat \
--with-libexpat-prefix=/opt/csw \
--with-x \
LDFLAGS="$(echo -n -Wl,-{L,R}/opt/csw/lib)" \
{CFLAGS,CPPFLAGS,CXXFLAGS}=-isystem/opt/csw/include

I don't recall the rationale behind all of the above options. Some of them
came from how the folks at opencsw.org build GDB, others were me just
banging on it until it compiled successfully (perhaps to my own detriment).

If you can offer any suggestions I would appreciate it.
