There are several ways to skin this cat, one solution would be adding
this to configure.ac

AC_DEFINE_UNQUOTED([HOST_OS], "$host_os", [target operating system])

Then in autoconfig.h you'll get something like this:

/* target operating system */
#define HOST_OS "solaris"

Then in your C code you can do something like this:

#if HOST_OS = "solaris"
#endif

Note: I'm not sure the exact string that solaris will produce for
HOST_OS, you'll just have to run autoreconf;configure and see how
HOST_OS gets defined, but "solaris" is a pretty good bet (note on linux
it's "linux-gnu")

If its a sparc only distinction you'll have to add "host_cpu" too.

I agree that autoconf/automake has a steep learning curve and at times
can be frustrating, but its the only viable game in town for open source
configuration and the definitive standard. Like it or not, its the right
way to do things. IMHO the autotool support that was added by Remi was a
huge improvement over the previous non-portable feature poor makefiles
(they couldn't even produce a debug static library, which is now trival
using automake).
