Description of problem: comments use the word "single" in 5 source
files for the word "signal".  Actually, "flag" might be a better term
as "signal" has other meanings in OS.


Version-Release number of selected component (if applicable): 2.3.3


How reproducible: look at source files or grep "single" in nptl/*.c
libc/nptl/pthread_mutexattr_getpshared.c
libc/nptl/pthread_mutexattr_gettype.c
libc/nptl/pthread_mutexattr_init.c
libc/nptl/pthread_mutexattr_setpshared.c
libc/nptl/pthread_mutexattr_settype.c
