Please implement and make available the <stdbool.h> and other missing headers like <inttypes.h> etc. from C99 and C++'s <cinttypes.h> (reported on Connect: http://connect.microsoft.com/VisualStudio/feedback/details/748766/) to VS2012's headers pool. It will help us porting open-source projects from other platforms to Windows ecosystem with ease. For an instance, the Giflib project (http://sourceforge.net/projects/giflib/) requires stdbool.h
Please show some love to C99 and C11 in your ongoing efforts.
