*** Changes since GDB 6.0:
* Removed --with-mmalloc
Support for the mmalloc memory manager has been removed, as it
conflicted with the internal gdb byte cache.

@ -2257,37 +2251,6 @@ of functions to indicate that they never return. The default is already
set correctly if compiling with GCC. This will almost never need to be
defined.
@item USE_MMALLOC
@findex mmalloc
@value{GDBN} will use the @code{mmalloc} library for memory allocation
for symbol 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{USE_MMALLOC}, you will also have to set
@code{MMALLOC} in the Makefile, to point to the @code{mmalloc} library. This
define is set when you configure with @samp{--with-mmalloc}.
@item NO_MMCHECK
@findex mmcheck
Define this if you are using @code{mmalloc}, but don't want the overhead
of checking the heap with @code{mmcheck}. Note that on some systems,
the C runtime makes calls to @code{malloc} prior to calling @code{main}, and if
@code{free} is ever called with these pointers after calling
@code{mmcheck} to enable checking, a memory corruption abort is certain
to occur. These systems can still use @code{mmalloc}, but must define
@code{NO_MMCHECK}.
@item MMCHECK_FORCE
Define this to 1 if the C runtime allocates memory prior to
@code{mmcheck} being called, but that memory is never freed so we don't
have to worry about it triggering a memory corruption abort. The
default is 0, which means that @code{mmcheck} will only install the heap
checking functions if there has not yet been any memory allocation
calls, and if it fails to install the functions, @value{GDBN} will issue a
warning. This is currently defined if you configure using
@samp{--with-mmalloc}.
@item NO_SIGINTERRUPT
@findex siginterrupt
Define this to indicate that @code{siginterrupt} is not available.
