Update.
1998-09-29 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * string/bits/string2.h (__string2_1bptr_p): Don't use a statement expression. (__mempcpy, strcpy, __stpcpy, strcmp, strcspn, strspn, strpbrk, __strsep): Greatly reduce size of expansion by combining common expressions. (__mempcpy_small, __strcpy_small, __stpcpy_small): Convert to inline function. (__mempcpy_args, __strcpy_args, __stpcpy_args): New macros, used by the above definitions.
