Add a patch from the Alpine Linux project to fix a musl build issue with gcc 5:
|
|
|
|
Problem has been reported upstream and closed with WONTFIX:

|
|
however...
|
|
|
|
POSIX does not permit using PTHREAD_COND_INITIALIZER except for static
|
|
initialization, and certainly does not permit using it as a value
|
|
|
|
POSIX does not specify the type of the object (it's opaque) so if
|
|
there are any types for which their code would be invalid C++, then their
|
|
code is invalid
|
|
|
|
Volatile in the type is necessary. without that, LTO can break the code.
