RFR 9: 8076184 Cleanup compile/link warnings on Solaris

[Roger Riggs]

Please review minor cleanups to compile and builds on Solaris.
Some entry points had been renamed but not updated in the 
make/mapfiles/reorder-xxx files
and a compilation warning remedied by putting declarations at the top of 
the .c file.
