Re: libstdc++-v3/libmath: cannot find math.h

[Shaun Jackman <sjackman at pathwayconnect dot com>]

I found that I have to build gcc with --enable-languages=c and install,
then build newlib and install, then build gcc with
--enable-languages=c++. Can this be done in one step without the
intervening installs?

Thanks,
Shaun
