Fix LibC++ Under Musl |
9 |
|
10 |
- Musl does not define locale-specific versions of functions (*_l) |
11 |
- This may be because musl only supports UTF-8 at the moment |
12 |
- This patch creates macros that redirect the *_l functions used to |
13 |
their non-localized variants. |
14 |
- Also, remove checks against GLIBC's version (EMSCRIPTEN) and |
15 |
__GLIBC_PREREQ (based on vvavrychuk's 3.4.2 patch). |
16 |
|
17 |
TODO: think about other LIBCs that might have confusing breakages due to |
18 |
last change. |
