-----------------------------------------+-----------------------
 I have a simple find-string-in-file program that uses boyer_moore
 matching.  On Mac, it compiles and works OK.  (Not sure if Mac is really
 using gcc; that's the command name, but "gcc -v" says "Apple LLVM version
 5.1 (clang-503.0.40) (based on LLVM 3.4svn)"

 At any rate, the same code, with a freshly-compiled Boost-1.56.0 on Debian
 7, gcc-4.7.2, fails to compile:

 (On Mac also, I compiled a fresh copy of Boost-1.56.0 using the native
 compiler.)
