And this has finally changed: since this recent commit, which will be part of upcoming 3.1.1 release, unrecognised configure options will result in an immediate error. And while the new behaviour is better, it does risk breaking a few of the existing build scripts, e.g. if you use obsolete options (such as --enable-compat24) or, indeed, if you made a typo in one of them. In this case, please just remove the options that don't exist any more (they were previously ignored anyhow) or fix the typos. And in the unlikely case when you really need to pass an unsupported option to wx configure script (why would you do this?), you can always explicitly use --disable-option-checking on the command line to continue doing so -- and you will even get an error if you make a typo in this one!

Configure is now less forgiving
Just a word of warning: it was previously possibly to write ../configure --enable-bloordyblop and configure would happily run and just ignore the unknown option. This could be seen as being nicely lenient but, in fact, was much more often aggravating as it allowed typos in configure options to slip through, resulting in many "WTF are my library binaries still not optimised even though I did use --enable-optimize?". The answer is, of course, as previously mentioned, wxWidgets British roots: you were supposed to use --enable-optimise instead. But while sticking to the right spelling might be commendable, not giving any errors for the wrongalternative one is definitely not. Moreover, this was never intentional and happened only as an unfortunate side effect of how Autoconf AC_CONFIG_SUBDIRS()macro worked
