--- Comment #5 from Thiago Macieira <thiago at kde dot org> --- (In reply to Thiago Macieira from comment #4) > If you're not going to fix the C header, can you please add an empty > libstdc++ header so that __STDC_VERSION_STDCKDINT_H__ won't get #define'd? Or wrap the C header with #ifndef __cplusplus.
