[LLVMdev] dragonegg build failure

[Duncan Sands]

Hi ether,

> i install mpc-0.8.2 in /home/ether/local/, and gcc-4.5 is configure with:
> $HOME/sources/gcc-4.5/configure --enable-plugin --enable-lto
> --prefix=$HOME/local/gcc-4.5/ --enable-languages=c,c++
> --disable-bootstrap --disable-multilib --with-mpc=$HOME/local
> --with-libelf=$HOME/local

because GCC headers include mpc.h, when dragonegg uses GCC headers then it needs
to be able to find mpc.h too.  You can pass it that info using CFLAGS as I
showed.  If you do that, does it build?

Ciao, Duncan.
