RE: Need ct-ng recipe for PPC toolset under Cygwin

["Diekema, Jon (GE Aviation, US)" <Jon dot Diekema at ge dot com>]

Remy got me started down a successful path with a Canadian build, but
the following patch was needed:

eglibc-2_14 patch: Add protection on the __caddr_t typedef in
usr/include/sys/types.h to avoid problems when caddr_t is defined.

When using ct-nt 1.13.0, the following patch for eglibc-2_14 was needed
for a i686-pc-mingw32-i686-pc-linux-gnu build.

Hi,

Why not build a canadian build under Linux?

With ct-ng on Linux you can build:
1) a linux->target toolchain
2) a linux->mingw toolchain
with these 1 and 2 you can build:
3) a mingw->target toolchain

Some advantages:
* Building the toolchain on Linux takes much less time.
* Much less troubles during the build since you are not bothered by
cygwin quirks.
* The mingw based toolchain performs much better on Windows resulting in
shorter build times as well.
* One Development environment for building all compiler toolchains.

Have Fun!

Kind Regards,

Remy
