another of the problems seems to be files over a certain size (complexity?)
causing strange errors, where unit tests work fine, but the larger programs
cannot be reduced to a smaller set for a unit test.

maybe I should complain about the ld file cache. it is causing problems too.
example:

C:\DOCUME~1\Barb\LOCALS~1\Temp\cc2hmuhd.o:find.cpp:(.text+0x837): undefined
reference to `compare_bool(std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> >,
std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator
<char> >, bool, unsigned int)'
collect2.exe: error: ld returned 1 exit status

this is not what's in the source file for a list of function arguments, this is
really old. an exe was generated anyway, but doesn't do anything.
