Isn't a missing pfb file always a fail, as the PDF-file would be broken
without it anyway, and one would have to repair something? If so, why
not write in t1_open_fontfile() of writet1.c instead of the warning:

        if (!t1_open())
            pdftex_fail("cannot open Type 1 font file for reading");

Or is there a case where a warning still would be ok?
