This reverts commit bf991bc0f3 and
fixes the bug instead. It's just sufficient to remove the defined()
test, since identifiers that aren't macros are just considered as
0 when used with #if. (see cpp info page, section 4.2.2 'If'
in cpp-4.6.info)
The code started to use #if defined(...) but the value was always
for GCC/Clang. The only difference was that for older compilers
the value of the definition was 0. Conditionally define these
macros.
Add a new core/defs.h file for definitions that can be used from
within header files without including prototypes and extern
declarations. It's primarily meant for macro definitions and basic
typedefs.
Move the definition of OSMO_DEPRECATED there and use compiler version
info to avoid compiler errors.
