// -DDONT_ADD_BYTE_AT_END disables the padding. |
// -DNO_SIGNALS does not disable signals during critical parts of |

// programs that call things like printf in asynchronous signal handlers. |
// -DGC_OPERATOR_NEW_ARRAY declares that the C++ compiler supports the |
// new syntax "operator new[]" for allocating and deleting arrays. |
// See gc_cpp.h for details. No effect on the C part of the collector. |
// This is defined implicitly in a few environments. |
// -DREDIRECT_MALLOC=X causes malloc, realloc, and free to be defined |
// as aliases for X, GC_realloc, and GC_free, respectively. |
// Calloc is redefined in terms of the new malloc. X should |
// be either GC_malloc or GC_malloc_uncollectable. |
// The former is occasionally useful for working around leaks in code |
// you don't want to (or can't) look at. It may not work for |
// existing code, but it often does. Neither works on all platforms, |
// since some ports use malloc or calloc to obtain system memory. |
// (Probably works for UNIX, and win32.) |
// -DNO_DEBUG removes GC_dump and the debugging routines it calls. |
// Reduces code size slightly at the expense of debuggability. |
