In the current glibc from CVS:

# find -type f | xargs grep stdbool.h
./elf/dl-load.c:#include <stdbool.h>
./elf/rtld.c:#include <stdbool.h>
./iconv/iconv_prog.c:#include <stdbool.h>
./iconvdata/tst-e2big.c:#include <stdbool.h>
./locale/programs/localedef.c:#include <stdbool.h>
./locale/programs/localedef.h:#include <stdbool.h>
./locale/programs/locarchive.c:#include <stdbool.h>
./locale/loadarchive.c:#include <stdbool.h>
./localedata/gen-unicode-ctype.c:#include <stdbool.h>
./malloc/memusage.c:#include <stdbool.h>
./nscd/grpcache.c:#include <stdbool.h>
./nscd/hstcache.c:#include <stdbool.h>
./nscd/pwdcache.c:#include <stdbool.h>
./nss/getXXbyYY_r.c:#include <stdbool.h>
./sysdeps/generic/ldsodefs.h:#include <stdbool.h>
./sysdeps/posix/readv.c:#include <stdbool.h>
./sysdeps/posix/writev.c:#include <stdbool.h>
./sysdeps/pthread/aio_suspend.c:#include <stdbool.h>

Since no header files use <stdbool.h>, I guess it may be ok.
