- Enabling it by default so that it gets tested. We should decide before
beta 2 if we want to revert back to malloc or not.

90bad130a9 MFZE1: If the size-operands of memset are constants, the compiler can turn them into fast inline code. So, instead of using ecalloc, we use emalloc + memset in macro form now. emalloc will not return NULL, so the chosen macro form is safe. This is not true for malloc(3). An inline function accomodates our needs here. Suggested by: http://www.mail-archive.com/dev%40httpd.apache.org/msg02492.html (Sascha) 2002-04-27 15:23:46 +00:00
