Pascal FINET - 2015-02-09

Since I update doxygen to 1.8.9, I get an error message at the end of the chm generation:

error: failed to run html help compiler on index.hhp

and of course, the CHM file is well generated.
I tried with an older version (1.7.4) and with the same project, I have some doxygen warning (expected due to new features) but no message of any html help compiler failure.

I'm working on Windows, and HHC is exiting with errorlevel = 1 when everything is OK.
