Whatever it means, ax_lua.m4 in some cases is broken and my goal was to improve it.
If Lua distributions put their headers in subdirectory, this doesn't mean that
all source packages around that use lua in their code will follow that convention.
Some will even bundle lua and make things worse.
For portability, /usr/include, /usr/lib /usr/bin are to be always the defaultand are relevant if you don't care about revisions.
The issue can be illustrated with a real example: dev-lua/luaposix-5.1.28
As expected, it will fail if you change AX_PROG_LUA(5.1, 5.3) toAX_PROG_LUA(5.2, 5.3).
The issue affects lua's library and interpreter as well.
