fix strstr, memmem, strcasestr
Wed Oct 6 09:31:00 GMT 2010
My strstr() implementation originally posted for newlib was also copied
to glibc, which means that newlib also suffers from this glibc bug:
[Normally, newlib is immune from glibc bugs because newlib won't pull in
LGPL code from glibc. But remember that as the original author of this
particular strstr() implementation, I exercised my right to dual-license
my code; so although glibc's use of the implementation is LGPL, newlib's
use is under a more-permissive license.]
Since it's a bug in my original implementation, and the fix is a single
line swap, I'm pushing the fix as obvious (whether the algorithm is
obvious is a different question).
