Software engineers - particularly of the more embedded variety - absolutely still have this problem.

The main culprit is GNU Make which does not cope with spaces in filenames. As far as it is concerned an array is a string separated by spaces so it gets very confused. Yes there are some partial workarounds, no none of them consistently work. You learn very quickly to check all code out in a file tree with no spaces in it, otherwise builds can randomly break in strange ways. It's not always clear up front whether Make is going to be involved somewhere in the build, so it's just easier to be safe.
