Subject: [PATCH] Define TARGET_OS_EMBEDDED in std{lib,io} if not defined
|
|
|
|
Originally attempted including `TargetConditionals.h` but this had
|
|
knock-on effects, for example, breaking the zlib build because of
|
|
`TARGET_OS_MAC` getting defined.
|
|
|
|
This should be the lowest impact solution and corresponds to the default
|
|
behavior IIUC.
