Outdated header files cause broken build on windows

[andrewklitzke]

sys/time.h is used in aslTimer. sys/time.h was removed in recent versions of visual studio (2008 i think?) and causes users to be unable to build ASL on a windows platform without some hacking.

Hi @andrewklitzke,

thank you very much for this bug report. We have rewritten the Timer class entirely to match the C++11 standard. Please, try recent commit and tell us whether it fixed your issue.

All the best.
