From b81d232a9bae21ef1bc896f106a926b66dcae869 Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN\"" Date: Sun, 11 Jul 2010 21:36:20 +0200 Subject: kernel: add mingw Add the option to build a cross-compiler for kernel type 'mingw'. The resulting cross-compiler can be used to build applications on a Linux host that can be run on a Windows target. Compiler is build using the mingwrt and w32-api packages aviable from the MinGW project (http://sourceforge.net/projects/mingw). The windows headers (w32-api package) are extracting with the kernel_headers step The libraries and other headers from both packages are build and installed in the various steps of libc Signed-off-by: Bart vdr Meulen [yann.morin.1998@anciens.enib.fr: fix kernel headers comment, don't "return 0"] Signed-off-by: "Yann E.
