[Spread-users] Spread 4 Solaris build failures

[Jonathan Stanton]

After a bit more reading it appears that using extern inline 
functions has a bunch of cases that different compilers handle 
differently. Specifically GCC does it differnt from most C99 compilers 
(see references below). 

I'll fix this up, either by giving up on inlining these functions,
removing the 'extern', or by making the variables they reference global
rather then file static. 

For the -rt case, do you happen to have a configure test that will check 
for this? If so I'll include it. If not I'll write one when I get a chance.
