Configure check for proper size_t printf() format
That "%ldd" should be "%lld"
- New version corrects "%lld"
This was a great pain to debug in msys2, but it turns out that %zu is valid format specifier for printf() (which we used in configure test), but not for our function declared with attribute((format(printf, ...)))
I have other fixes to this as well. Will submit a new version later.
New patch version
- Make sure that the build test has -Wall and -Werror set so that it fails for specifiers for which it should
- Added "checking..." outputs
- In the compilation test, call function defined with attribute((format(printf, ...))) instead of printf()
Crosser based build fails with the current patch version. It would expect "%I64d"
Support for "%I64d" added in latest version
For better support of using size_t variables in the printf() family of functions, add a configure check for determining which kind of specifier should be used for them. This ticket is about autotools implementation, though care should be taken not to completely break meson build.
