After the latest updates, pdftex and luatex compilations always end with these two warnings:
pdfTeX warning: pdflatex.exe (file C:/Users/Rah/AppData/Local/MiKTeX/2.9/pdftex
/config/pdftex.map): invalid entry for '\def\filedate{2015/12/30}': both ps_nam
e and font file missing
pdfTeX warning: pdflatex.exe (file C:/Users/Rah/AppData/Local/MiKTeX/2.9/pdftex
/config/pdftex.map): invalid entry for '\def\fileversion{1.2}': both ps_name an
d font file missing
The faulty lines are in verdana.map (in fonts/map/pdftex/ms/verdana
if my memory is correct). If you delete them from there and then run
initexmf --mkmaps the problem should be gone.
I suspect an error in verdana.dtx and already informed the author.
Thanks Ulrike, that's it.
