This is a namespace conflict.  The Solaris stream.h defines struct bcache
which is also defined by GDB in bcache.h; the latter is being included
unnecessarily in the files ser-unix.c, ser-pipe.c, and ser-tcp.c.

I was able to get the m68k-elf target to build by adding:

#define BCACHE_H 1

at the top of each of these files.  Not that I'd submit that as a patch ;-)
but this allows me to build native Solaris and m68k-elf targets.

Hopefully someone more familiar with the code can come up with a more
elegant solution?
