* Merge index() and strchr() together.ed2012-01-031-4/+3
| | | | | | | | | | | | | | | | | As I looked through the C library, I noticed the FreeBSD MIPS port has a hand-written version of index(). This is nice, if it weren't for the fact that most applications call strchr() instead. Also, on the other architectures index() and strchr() are identical, meaning we have two identical pieces of code in the C library and statically linked applications. Solve this by naming the actual file strchr.[cS] and let it use __strong_reference()/STRONG_ALIAS() to provide the index() routine. Do the same for rindex()/strrchr(). This seems to make the C libraries and static binaries slightly smaller, but this reduction in size seems negligible.

* Change the test at the beginning of strncmp(), from being if (len - 1) < 0cognet2009-04-281-4/+4
| | | | | | | | | to if (len == 0). The length is supposed to be unsigned, so len - 1 < 0 won't happen except if len == 0 anyway, and it would return 0 when it shouldn't, if len was > INT_MAX. Spotted out by: Channa <channa kad gmail com>
