6152	Linker warning mktemp is dangerous	Andreas Heuermann	Martin Sjölund	"When compiling omc we get warnings that some functions like `mktemp` and `tmpnam` are dangerous and should be replaced.

Annoying but not really a problem (besides security concerns of course).

When compiling Modelica models with OMEdit users will get the same errror message in the ""Compilation"" tab.

This will raise questions for a lot of users if they did something wrong when building a model."	defect	new	normal		Build Environment	v1.17.0-dev		linker, mktemp, tmpnam
