------- Additional Comments from Harald Fernengel <harry at kdevelop.org>
DateMath.cpp calls abs(long int) - which is ambiguous in some tool chains, for
example on QNX:
/home/harald/qt/qt/src/3rdparty/webkit/JavaScriptCore/wtf/DateMath.cpp: In
function 'double WTF::parseDateFromNullTerminatedCharacters(const char*)':
/home/harald/qt/qt/src/3rdparty/webkit/JavaScriptCore/wtf/DateMath.cpp:844:
error: call of overloaded 'abs(long int&)' is ambiguous
/opt/qnx640/target/qnx6///usr/include/stdlib.h:122: note: candidates are: int
std::abs(int)
/opt/qnx640/target/qnx6///usr/include/math.h:1042: note: long
double std::abs(long double)
/opt/qnx640/target/qnx6///usr/include/math.h:692: note: float
std::abs(float)
/opt/qnx640/target/qnx6///usr/include/math.h:624: note: double
std::abs(double)
make[1]: *** [obj/debug/DateMath.o] Error 1
Patch replaces the abs() call to labs(), which takes a long int and returns a
long int. This also removes two implicit casts.
