Subject: [PATCH] threads: use forward declarations only for glibc (fixes
|
|
#704908)
|
|
|
|
The declarations of pthread functions, used to generate weak references
|
|
to them, fail to suppress macros. Thus, if any pthread function has
|
|
been provided as a macro, compiling threads.c will fail.
|
|
This breaks on musl libc, which defines pthread_equal as a macro (in
|
|
addition to providing the function, as required).
|
|
|
|
Prevent the declarations for e.g. musl libc by refining the condition.
|
|
|
|
The idea for this solution was borrowed from the alpine linux guys, see
|
|
