malloc undefined cross compiling with gcc 3.4.3 for mingw32

[Mr E_T]

I have installed the cross toolchain with -
 
 binutils 2.15.94.0.2
 configure --prefix=/opt/compilers --host=i486-pc-linux-gnu \
 --build=i486-pc-linux-gnu --target=i486-mingw32 --infodir=/tmp \
 --mandir=/tmp --datadir=$PREFIX/i486-mingw32/share
 make
 make gnulocaledir=/tmp localedir=/tmp install
 
 gcc 3.4.3
 configure --prefix=/opt/compilers -host=i486-pc-linux-gnu \
 --build=i486-pc-linux-gnu --target=i486-mingw32 --infodir=/tmp \
 --enable-threads=win32 \
 --mandir=/tmp --datadir=$PREFIX/i486-mingw32/share
 make
 make -C gnatlib
 make gnulocaledir=/tmp localedir=/tmp install
 
 w32api 3.2
 configure --prefix=/opt/compilers/i486-mingw32 --build=i486-pc-linux-gnu \
 --host=i486-mingw32 --target=i486-mingw32
 make
 make install
 
 mingw-runtime 3.7
 configure --prefix=/opt/compilers/i486-mingw32 \
 --build=i486-pc-linux-gnu --host=i486-mingw32 --target=i486-mingw32
 make
 make install
 
 wxWidgets 2.6.0
 configure --prefix=/opt/compilers/i486-mingw32 --mandir=/tmp --infodir=/tmp \
 --build=i486-pc-linux-gnu --host=i486-mingw32--enable-optimise \
 --with-libpng --with-libjpeg --with-libtiff \
 --with-zlib --without-sdl --enable-odbc --disable-monolithic --enable-threads
 make
 make install
 mv /opt/compilers/i486-mingw32/lib/wx*.dll /opt/compilers/i486-mingw32/bin
 
 Everything worked well including the other libraries - zlib, jpeg etc.
 
 I then tried aMule 2.0.1 -
( Compiles perfectly with wxgtk under linux with same toolchain version )
No matter what I do what options I use to compile the cross compiler or wxwidgets 
I get the same problem.

 configure --host=i486-mingw32 --enable-amule-gui --enable-amulecmd \
 --enable-amulecmdgui --enable-amule-daemon --enable-webserver \
 --enable-webservergui --enable-alc --enable-alcc --enable-cas --enable-wxcas \
 --with-wx-prefix=/opt/compilers/i486-mingw32
 make
 and got the following fatal errors ( in a number of files ) -
 if i486-mingw32-g++ -DHAVE_CONFIG_H -I. -I. -I.. -I/opt/comilers/i486-mingw32/include \

 My problem is the malloc thing.
 
 Any help would be appreciated.
 
 Thanx

<cstdlib> includes <stdlib.h>.  <stdlib.h> is supposed to declare
malloc.  Apparently, it doesn't, and that is what the compiler is
complaining about.

This is not a compiler bug, unless there really is a declaration of
malloc and the compiler is somehow ignoring it.  This is a library bug
of some sort.

Actually cstdlib undefines malloc and realloc in favour of std::malloc std::realloc

Then it cant find the std:: functions.

I am having a similar problem compiling a cross gcc for uclibc with thier patches.
but with snprintf instead. ( same std::snprintf member not existing thing )

Part of my problem I have found is that gcc will ignore certain error while building - 
thus hiding the fact that they occured. (libstdc++)

I am beginning to think that I have a problem that is being passed on from my previous 
compiler. But I dont see how.

I cant even build gcc-4.0.0 without errors at the moment. - It cant find existing files.
