Hi Bernhard,
Below is cygwin-2.patch, which takes your recommendations into account,
proceedings for cygwin-1.patch still apply.
Another issue I ran into now is the following for building the host
gdb.exe, let me know if this is worth a separate thread:
make[1]: Leaving directory
`/tw/buildroot/toolchain_build_arm/gdbhost-6.6'
strip /tw/buildroot/toolchain_build_arm/gdbhost-6.6/gdb/gdb
strip: /tw/buildroot/toolchain_build_arm/gdbhost-6.6/gdb/gdb: No such
file or directory
make: *** [/tw/buildroot/toolchain_build_arm/gdbhost-6.6/gdb/gdb] Error 1
The problem is that gdbhost-6.6/gdb/gdb does not exist.
gdbhost-6.6/gdb/gdb.exe does exist (and works fine) and should not be
stripped. Where should the cygwin exclusion for this happen?
Thanks
Tom

+ Where possible, use static libraries.
+ This increases your code size a lot and should only be

+ If unsure, say No.
