Temporary patch to fix Clang incompatibility before upstream commit.
|
||||

|
||||
Apply asm redirections in stdio.h before first use [BZ #27087]
|
||||
|
||||
Changes since v1:
|
||||
- Removed the duplicated inclusion of bits/floatn.h.
|
||||
|
||||
I plan to backport this fix to at least glibc 2.35.
