GDB will use the @code{mmalloc} library for memory allocation for symbol
reading, unless this symbol is defined. Define it on systems
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.
Therefore, this define is usually set on the command line by overriding
@code{MMALLOC_DISABLE} in @file{config/*/*.mh}, rather than by defining
it in @file{xm-*.h}.
