I probably should have been clearer. ANSI C requires that free(NULL) should
have no effect. Pre-ANSI compilers may very well have not followed this
rule.
The whole ANSI C effort has been hobbled by the fact that there was so much
C code out there that depended on existing compiler quirks. The standard
ended up being fairly toothless, especially in the requirements of the
standard library functions.
