New Revision: 251665
URL: http://llvm.org/viewvc/llvm-project?rev=251665&view=rev
Log:
Revert r249929 ("Split <string.h> out of <cstring>").
This change caused problems when building code like povray that:
a) uses 'using namespace std;'
b) is built on an environment where the C library provides the "wrong"
(non-const-correct) interface for the str* functions
c) makes an unqualified call to one of those str* functions
A patch is out for review to add a facility to fix this (and to give the
correct signatures for these functions whenever possible, even when the C
library does not do so). This revert is expected to be temporary.
