It's been suggested on the other thread that he works at Netgem: http://fr.wikipedia.org/wiki/Netgem (sorry, the link is in French, but it's been deleted from Wikipedia EN). Wikipedia FR for Fabrice Bellard supports this claim.

A quick google for "fabrice bellard netgem" shows his email address at Netgem and a slew of C header/source files copyrighted Netgem and written by him, so he was definitely working there at some point.
