duplicate link objects with scons #226

Open GoogleCodeExporter opened 8 years ago

If I rebuild using scons having changed a compile flag that rebuilds the VM (I 
added /Zi) the lib step says
src\vm\pmstdlib_img.obj : warning LNK4042: object specified more than once; 
extras ignored
src\vm\pmstdlib_nat.obj : warning LNK4042: object specified more than once; 
extras ignored

It's caused by src/vm/SConscript using a wildcard that finds the pmstdlib_img.c 
and pmstdlib_nat.c generated the last time round.
SOURCES = Glob("*.c")
If this is changed to filter out the pmImgCreator.py generated C files the link 
warnings do not occur
PMSTDLIB_GENERATED = ["pmstdlib_img.c", "pmstdlib_nat.c"]
possSOURCES = Glob("*.c")
SOURCES =[x for x in  possSOURCES if x.name not in PMSTDLIB_GENERATED]
