...afraid yes...

OPT_CFLAGS = -march=pentium4 -mmmx -msse -msse2 -mfpmath=sse -O2 

[I don't think -mmmx does anything of value here, but I just transferred 
over my Gentoo CFLAGS for consistancy ;-) ]

I'll have to look into these DAZ and FTZ switches, as were discussed on 
the LAD list. But it's really a pity that it's so difficult to get good 
performance out of a P4. This is why I can only *un*recommend them to 
anybody wanted to do audio.

Off to Ebay I go for a new laptop. When will PD have a 64bit version so 
I can check out one of these new AMDs? ;-)
