Work around MinGW GCC version >=4.5 always_inline+dllexport bug.
Work around MinGW GCC version >=4.5 always_inline+dllexport bug.

Use regular inline instead of always_inline for MinGW GCC build. GCC 4.5
and later spit out an error on always_inline dllexport functions, which
breaks the build for these versions of GCC (see bug 5938).
