VQ has merged all updated patches to cws_srx645_mingw.
I am working on it. It has stopped at sal.
Most difficult part of this build is to rebuild bintutils and libmsvcrt.a.
You need the binutils source, psuedo-reloc and resres patches, mingw-runtime-3.2-src.tar.gz, w32api-2.5-src.tar.gz, and even bison and flex to build them, and also msys and its tool kits.
This is a mountain for me. Mt. Kurikoma spans Miyagi Pref., Akita Pref. and Iwate Pref. Miyagi people call it Kurikoma. Iwate people call it Sukawa. Akita people call it ..... I don't know. The same mountain is called different names. The same river is called different names like Donau and Vltava.
To prepare the tool to build cws_srx645_mingw is for me just like swimming Vltava and climbing Sukawa
