From f9f33cdc78b5893a4764b1437b59536f399a50d1 Mon Sep 17 00:00:00 2001

Subject: Allow disabling "inline"

Compiler support for inline is sometimes buggy, and occasionally
missing entirely.  This patch adds a test for inline support, and
redefines the keyword with the preprocessor if necessary at compile
time.
