Be forewarned that writing documentation is not one of my strong points. Because of limitations of the stock Windows command shell backslash characters can be problematic and should not be used in arguments to configure. That means that forward slashes must be used in paths passed to the compiler and linker via the --cflags and --ldflags options. Note that it is possible to pass a macro like -DFOO=BAR via the --cflags and --ldflags options as long as it is enclosed in quotes. The code that parses the --cflags and --ldflags options removes any surrounding quotes (but only if command extensions are available). If command extensions are disabled, an attempt will be made to enable them. If command extensions are not available a warning message will be displayed informing you that "using parameters that include the = character by enclosing them in quotes will not be supported." Note that at this time only the --cflags and --ldflags options support using the = character. The = character will be treated as a separator character for all other options. This is part of the patch I am working on to provide support for --cflags and --ldflags options like -DFOO=BAR. Please let me know what you think of this change. Also, I need to know if the following comments in configure.bat are still valid. Rem WARNING -- COMMAND.COM on some systems only looks at the first Rem 8 characters of a label. So do NOT be tempted to change Rem chkapi* into something fancier like checkw32api Rem You HAVE been warned! I would like to know if I can safely use labels that are longer than 8 characters now.
