Subject: [PATCH 199/411] Define _GNU_SOURCE on Linux for mremap()
|
|
|
|
This was committed to CPython's libffi copy in
|
|
https://bugs.python.org/issue10309
|
|
|
|
mremap() documentation says _GNU_SOURCE needs to
|
|
be defined in order to use mremap(): see the
|
|
synopsis section at http://linux.die.net/man/2/mremap
|
|
|
|
Original commit: https://hg.python.org/cpython/rev/9986fff720a2
|
|
|
|
Original patch was written by Hallvard B Furuseth.
