Summary

0001032: omnetpp-5.3p3 does not build on debian Jessie

Description

Compilation of the preview 3 of 5.3 does not compile on debian Jessie because some builtin functions can not be found.
Preview 2 worked fine.

cdynamicexpression.cc:385:9: error: use of undeclared identifier '__builtin_add_overflow'
    if (__builtin_add_overflow(a, b, &res))
        ^
cdynamicexpression.cc:397:10: error: use of undeclared identifier '__builtin_mul_overflow'
    if ( __builtin_mul_overflow(a, b, &res))
         ^

Debian clang version 3.5.0-10 (tags/RELEASE_350/final) (based on LLVM 3.5.0)
Target: x86_64-pc-linux-gnu
Thread model: posix

It looks like the llvm 3.5 toolchain only supports add and mul for short and unsigned:
