/* For a platform with CR/LF, additional logic is required by

__sgetc_r which would otherwise simply be a macro; therefore we

use an inlined function. The function is only meant to be inlined
|
|
in place as used and the function body should never be emitted.
|
|
|
|
There are two possible means to this end when compiling with GCC,
|
|
one when compiling with a standard C99 compiler, and for other
|
|
compilers we're just stuck. At the moment, this issue only
|
|
affects the Cygwin target, so we'll most likely be using GCC.
|
|
|
|
The traditional meaning of 'extern inline' for GCC is not
|
|
to emit the function body unless the address is explicitly
|
|
taken. However this behaviour is changing to match the C99
|
|
standard, which uses 'extern inline' to indicate that the
|
|
function body *must* be emitted. If we are using GCC, but do
|
|
not have the new behaviour, we need to use extern inline; if
|
|
we are using a new GCC with the C99-compatible behaviour, or
|
|
a non-GCC compiler (which we will have to hope is C99, since
|
|
there is no other way to achieve the effect of omitting the
|
|
function if it isn't referenced) we just use plain 'inline',
|
|
which c99 defines to mean more-or-less the same as the Gnu C
|
|
'extern inline'. */
