/* This test checks the variations on inline function defintions.

|
* "static inline int func(void) {...}"
|
|
*
|
|
* Consistent meaning in C89, C99, and C++ (98 and 11).
|
|
* If not inline'd results in a private symbol in each compilation unit.
|
|
* Thus the non-inline'd version is duplicated in each compilation unit.
|
|
* However, definitions in different compilation units may be different.
|
|
*
|
|
* "inline int func(void) {...}"
|
|
* Warning: Not consistent, avoid use in headers meant for C or C++
|
|
*
|
|
* In C++ this may be safely defined in more than one compilation unit.
|
|
* Where not inlined it will result in a weak public symbol.
|
|
* Thus non-inline'd version isn't duplicated, but must be the same
|
|
* in all compilation units.
