I think GCC version is not a problem but the configure flags
and building procedures are the problem.
So I got it compiled by cheating. Because building gcc will lead
to errors of missing header files, I installed the C32 student
version under Wine and copy the header files to the
directory /opt/pic32mx/pic32mx/include. The GCC can be built.
Building gdb will fail but anyway it is not included in the
Microchip C32 compiler either.
export TARGET=pic32mx
export PREFIX=/opt/$TARGET
export PATH=$PATH:$PREFIX/bin
./configure --target=$TARGET --prefix=$PREFIX --with-gnu-as --with-gnu-ld \
--with-headers=$prefix/$target/include --enable-languages=c
Building the binutils first and install it. Then go to the as and ld
folder and build/install them. After that, gcc can be build.
gdb failed to be built.

I know this is not right procedure but I am not so sure how to bypass
the missing header file errors when building gcc.
I asked the question in Microchip forum because I am afraid that
there are something missing.
