See attached patch and the diffstat below:

 configure        |   48 +++++-------------------------------------------
 print_env_info.c |   35 +++++++++++++++++++++++++++++++++++
 2 files changed, 40 insertions(+), 43 deletions(-)

I suggest we include it and then release tomorrow once people checked I didn't 
break something with my last patches.

Best regards,

Thomas
