As it seems, different C compilers have different rules/interpretations on inline functions. The current code base did not properly obey all C99 rules. We fix this by converting some functions to macros and others to include the necessary C99 plumbing. We also remove some inline attributes for functions where this seems to be to agressive (aka "function to big"). This fixes build problems in some environments and is a general code cleanup measure.
