______________________________________
It seems that "" around path to build folder is missing.

Yes, some "  would be useful there.

The problem with $buildPath is that it can be chained with other strings, for example in avr-gcc compiler:
$buildPath$fileName.elf

But I did some testing, and adding quotes only to $buildPath seems to work ok, which I didn't know.

For example:
$filePath = /path/toMyproject/mycode.c
$buildPath = /path/toMyproject/build/
$fileName = mycode

Executing this works ok:
"/path/to/avr-gcc" -g -o "/path/toMyproject/build/"mycode.elf "/path/toMyproject/mycode.c"

So SimulIDE will add quotes to $buildPath.

I'm also adding native separators because some programs like Asem51 only accept these.

I think it should be solved at trunk Rev 1822.
