@changtengfei and @TimothyClaeys
hey guys this relates to the issue I posted some days ago: https://openwsn.atlassian.net/jira/software/c/projects/FW/issues/FW-887

it fixes additional warnings and errors for IAR compiler, these changes do not interfere with the scons build script, they still produce the same output as before

BR Chris

It seems that something with fragmentation fails for python which I haven't touched hope thats something you can have a look at and it does not block the PR

@Chris-Ho Thank you for the PR. I'll have a look at why it fails during the Travis build.

@TimothyClaeys thank you I found an indicator for it and updated the PR

bsp/boards/python/openwsnmodule_obj.h required an update which depends on the newly introduced configuration options

as side note on windows latest develop branch can not be compiled for python, which has maybe the same root cause as for IAR that some o those socket related code is not correctly suppported. I'm using gcc version 6.3.0 (MinGW.org GCC-6.3.0-1)

@TimothyClaeys everything is solved now, windows works as well
