Hello,
This one makes system.h pull in <cstdlib> when compiling as C++.
It fixes issues when e.g. including <algorithm>.
Tested on my SH cross compiler config with 'make all-gcc', after
including the following std headers in one of the RTL passes:
<algorithm> <limits> <bitset> <cassert> <cctype> <cerrno> <cfloat>
<climits> <clocale> <cmath> <complex> <csetjmp> <csignal> <cstdarg>
<cstddef> <cstdio> <cstdlib> <cstring> <ctime> <deque>e <exception>
<fstream> <functional> <iomanip> <ios> <iosfwd> <iostream> <istream>
<iterator> <limits> <list> <locale> <map> <memory> <new>e <numeric>
<ostream> <queue> <set> <sstream> <stack> <stdexcept> <strstream>
<streambuf> <string> <typeinfo> <utility> <valarray> <vector>.
My host GCC is:
gcc -v
Using built-in specs.
