Clean up string functions that do not have a version in gnulib on the assumption that glibc is the canonical upstream copy of this code. basename has a copy in gnulib but it is largely written to handle Windows paths so merging it is not really viable. The changes mostly consist of switching to ANSI function prototypes and removing unused includes. As many of these functions do not get built in a typical build due to architecture optimized versions being used instead I built these by hand to verify there were no build warnings and the code was identical. 2014-04-07 Will Newton <will.newton@linaro.org> * string/basename.c [HAVE_CONFIG_H]: Remove #ifdef and and contents. [!_LIBC] Remove #ifndef and contents. (basename): Use ANSI prototype. [_LIBC] Remove #idef. * string/memccpy.c (__memccpy): Use ANSI prototype. * string/memfrob.c (memfrob): Likewise. * string/strcoll.c (STRCOLL): Likewise. * string/strlen.c (strlen): Likewise. * string/strtok.c (STRTOK): Likewise. * string/strcat.c: Remove unused #include of memcopy.h. (strcat): Use ANSI prototype. * string/strchr.c: Remove unused #include of memcopy.h. (strchr): Use ANSI prototype. * string/strcmp.c: Remove unused #include of memcopy.h. (strcmp): Use ANSI prototype. * string/strcpy.c: Remove unused #include of memcopy.h. (strcpy): Use ANSI prototype.
