Integrate two DJGPP portability patches from the 5.6.2 branch :
[20859]
Two portability patches for DJGPP from Richard Dawe
<rich@phekda.freeserve.co.uk>.
Message-Id: <E19qfNh-0000Zq-00@phekda.freeserve.co.uk>
[20911]
Don't uppercase automatically all environment variables on DJGPP.
(reported by Richard Dawe, this breaks portability of Unix
scripts.) Don't change the behaviour on plain MS/DOS.
