This is just notes that will be reordered and elaborated on later.

== What to look out for... ==

 - dos.m4 - Add {{{ && !defined __OS2__}}} to the long {{{#if}}} statement. See [3345] for an example.
 - po.m4 - Fix the root slash detections. See [3344] for an example.
 - Absolute paths. Try get rid of these, if not possible prefix with {{{/@unixroot}}} or {{{$UNIXROOT}}}.
 - Check for CYGWIN, WIN32, WINDOWS, MINGW or similar defines.
 - Add calls to {{{_wildcard(&argc, &argv); _response(&argc, &argv);}}} in the main function of tools that it may be more useful if the supported wildcard and response files when invoked from a non-kNIX shell.
 - Check if there is a {{{lib/system.h}}} and check the {{{SET_BINARY_MODE}}} definition.
 - Tools reading stdin or writing to stdout, needs to be checked in respect to binary/text mode translation. This isn't as simple as just doing setmode on stdin and stdout in main...
 - {{{aclocal}}}, {{{aclocal.in}}}, {{{atconfig}}} and {{{atconfig.in}}} in testcase directories (typically {{{tests}}}). Fix the PATHs and other stuff they mess with.

''The .m4 files to are usually located in a m4 or config subdirectory.''
