With ncurses-6.0-20170701.patch
|
||
|
|
|
||
|
|
+ improve compatibility between different configurations of new_prescr,
|
||
|
|
fixing a case with threaded code and term-driver where c++/demo did
|
||
|
|
not work (cf: 20160213).
|
||
|
|
|
||
|
|
the pthread_self(3) function call had been called without checking if the
|
||
|
|
library libpthread has been linked. This break e.g. grub (boo#1058509) if
|
||
|
|
statically linked.
