system.h: Use putc_unlocked...
* system.h: Use putc_unlocked, fputc_unlocked, and
fputs_unlocked only if putc_unlocked has a prototype already.
Prototype fputs_unlocked if necessary.
* configure.in: Check for prototypes of putc_unlocked and
fputs_unlocked.
* acconfig.h: Updated.
* config.in, configure: Rebuilt.
