Containers & Iterators sanity check

I'm using g++ 3.4.2 & am having trouble with algorithms (find) and
strings. Here's my code:

string::iterator itor = find(input.begin(), input.end(), "|");

I'm fairly sure this code worked for me in the past, as I am working out
of the same reference material I have used on previous compilers. I just
can't figure out why I am getting the following error:

/usr/lib/gcc/i386-redhat-linux/3.4.2/../../../../include/c++/3.4.2/bits/stl_algo.h:207:
error: ISO C++ forbids comparison between pointer and integer
Any help would be greatly appreciated.

I'm fairly sure this code *never* worked. However, this will:

string::iterator itor = find(input.begin(), input.end(), '|');

The key difference is to pass a character rather than string literal
as the value argument.

Argggh! I could have looked at that code all night & not seen the double
quotes. Thanks.
