 HI Romain,
 
 Yes, that's the output I was expecting, so you can commit the change
 whenever you're ready. Thank you for the explanation about the 'configure'
 script -- it does make a lot of sense for Mono to package the sources like
 that now that you mention it.
 
 Regards,
 Jack

 The 'configure' script is generated by the autotools from the
 'configure.in' file.  So modifying the 'configure.in' file require you to
 run all the autotools chain to regenerate the 'configure' script before
 continuing.  This is the reason you had to run 'autogen.sh'.
 
 When the mono folks release a new mono tarball, they include the generated
 'configure' script in it so we have to either patch 'configure.in' and
 re-run the whole autotools chain, or patch the generated 'configure' which
 avoids us all the mess that commes with the autotools if we have to change
 something there.

 I get:

 	TLS:           __thread

 which is what you are expecting, right ?  Then I guess I can commit this
 change.
