No it shouldn't do any harm. 

'[cpp]' section in djgpp.env is stale anyway gcc since gcc-2.95.3 uses 
cpp0 instead of cpp (gcc-3.0 uses cpp0 only in some cases, eg. when 
dumping preprocessed source is required)

It seems that this outdated stuff  shouldn't harm anybody

If we have more that one cxxfilt.exe then at least I see which one 
printed version. Of course it's ugly, but could somethimes be usefull
