Apart from removing the inline stuff in ctype.h it seems to be no way to
avoid the ABI breakage without problem or other troubles.  The inlined
functions are usually used in a loop which may have some impact to
performance, I think we need to do some actual benchmark before
concluding anything, but no, I'm not inclined for that approach yet.
