Since _Csys_alloc() calls malloc, I want to replace malloc, not _Csys_alloc. If you prefer a smaller application and don't need the additional functionality of the C99 or C++ libraries, you should use Redlib, which can can produce much smaller applications. specs, but they appear to be adding a library group instead of replacing the default. Newlib is a C library intended for use on embedded systems. FreeRTOS incorporates that into the task control block (TCB) and handles allocating and deallocating it, but it's pretty large - I think it was on the order of 1.
