on which @code{mmalloc} does not

reading if this symbol is defined. Be careful defining it since there

are systems on which @code{mmalloc} does not

work for some reason. One example is the DECstation, where its RPC
|
||||
library can't cope with our redefinition of @code{malloc} to call
|
||||
@code{mmalloc}. When defining @code{NO_MMALLOC}, you will also have
|

to override the setting of @code{MMALLOC_LIB} to empty, in the Makefile.
