GCC 2.95.1 on SPARC/Solaris, at least, is clever enough to figure out

GCC 2.95.1 on SPARC/Solaris, at least, is clever enough to figure out
that the loop in "lanalyzer_open()" is an infinite loop, so the "return
0;" at the end isn't necessary to suppress a compiler warning with that
compiler - and Sun C not only figures it out, it warns that the
"g_assert_not_reached()" and the "return 0;" are unreachable, so I'll
take them out for now (and put them back if my older GCC at home still
requires it to suppress warnings).
