<string.h>: Define __CORRECT_ISO_CPP_STRING_H_PROTO for Clang [BZ #25232]
|
||
|
|
|
||
|
|
Without the asm redirects, strchr et al. are not const-correct.
|
||
|
|
|
||
|
|
libc++ has a wrapper header that works with and without
|
||
|
|
__CORRECT_ISO_CPP_STRING_H_PROTO (using a Clang extension). But when
|
||
|
|
Clang is used with libstdc++ or just C headers, the overloaded functions
|
||
|
|
with the correct types are not declared.
|
||
|
|
|
||
|
|
This change does not impact current GCC (with libstdc++ or libc++).
