_GL_EXTERN_INLINE is a portable alternative to 'extern inline'.

_GL_INLINE_HEADER_BEGIN contains useful stuff to put

in an include file, before uses of _GL_INLINE.
|
|
It suppresses GCC's bogus "no previous prototype for 'FOO'" diagnostic,
|
|
when FOO is an inline function in the header; see

<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54113>.

_GL_INLINE_HEADER_END contains useful stuff to put

in the same include file, after uses of _GL_INLINE. */
