    The TivaWare Graphics Library User's Guide contains the following in the description of the tFontEx typedef:

    This is a newer version of the structure which describes a font used for drawing text onto the screen. This variant allows a font to contain an arbitrary, contiguous block of codepoints from the 256 basic characters in an ISO8859-n font and allows support for accented characters in Western European languages and any left-to-right typeface supported by an ISO8859 variant. Fonts encoded in this format may be used interchangeably with the original fonts merely by casting the structure pointer when calling any function or macro which expects a font pointer as a parameter. More information on this and the other supported font structures may be found in the “Font Format” section of the user’s guide.

    Which suggests to remove the warning you need to add a cast. E.g. try:

    GrContextFontSet(&sContext, (const tFont *) &g_sFontExHhb60);

    Note that I haven't attempted to test this.
