I'll have to modify my patch... Regards, Stefan W.

Glib2 uses __printf__ in macro G_GNUC_PRINTF for printf like functions. For MinGW, we want __gnu_printf__ because we use POSIX format specifiers instead of the MS format specifiers. Signed-off-by: Stefan Weil <sw@weilnetz.de> --- configure | 2 ++ 1 file changed, 2 insertions(+)
