C++Builder’s CRTL now uses FastMM as built-in memory manager. You can see this in “source\cpprtl\Source\memory\_fastmm.c”. It has also AUTO_SHARE_MEMORYMANAGER defined what means that it can work with the Delphi FastMM memory manager and the BorlndMM.dll isn’t necessary anymore.
There are also some optimized c-string and memory functions in the CRTL code. Looks like somebody got rid of the 1992/93 implementations.
