Here is a link describing what's going on:
http://gcc.gnu.org/gcc-4.4/porting_to.html
Scroll down a bit to the "Strict null-terminated sequence utilities"
section, and you'll see how things have changed in the interest of
const-correctness for GCC 4.4.
r30919 was the first instance I saw a fix in this regard,
Basically, with GCC 4.4, if something like strchr is fed a const char*
, it's going to return a const char* . This can then become
problematic, like has shown to be the case here.
I assume some kind of casting will have to be done. Will utilizing
const_cast or the like be the way to go? I'm currently testing other
breakage, so will wait to update my Linux compiler to do further
testing in this regard.
