Subject: [PATCH 31/N] uname: allow setting the system name to CYGWIN
|
|
|
|
We are currently trying to move our cygwin build environment closer
|
|
to cygwin and some autotools/bash based build systems call "uname -s"
|
|
to figure out the OS and in many cases only handle the cygwin case, so
|
|
we have to patch them.
|
|
|
|
With this instead of patching we can set MSYSTEM=CYGWIN and change
|
|
uname output that way.
|
|
|
|
The next step would be to always output CYGWIN in an msys env by default,
|
|
but for now this allows us to get rid of all the patches without
|
|
affecting users.
