// notes:
// - this file is included in the PCH and thus affects the entire project.
//   to avoid unnecessary full rebuilds, place settings of more limited
//   applicability in config2.h and explicitly include that header.
// - config macros are always defined; their values (1 or 0) are tested
//   with #if instead of #ifdef. this protects against typos by at least
//   causing a warning if the tested macro is undefined.
// - allow override via compiler settings by checking #ifndef.
