[PD] ICC compile [or: PD + P4 + Linux = massive headache!]

Tim,

I compiled perfectly fine with ICC using CC=icc and CXX=icc flags. I 
will start testing to see if it fixes some of my problems tonight, and 
maybe try some other flags for different optimizations. Results to this 
list soon.

It is a completely normal configure, except that it ignores ICC and uses 
GCC. See for yourself below. I even tried --disable-gcc, and it ignored 
that. The two flags you mention: --enable-optimize=pentium4 and 
--enable-icc do *not* appear when I type ./configure --help, although 
many others do.

I also recall that I could not set the OPT_CFLAGS in the ./configure 
stage, I actually had to enter them manually in the "configure" file. 
According to ./configure --help, this should be possible.

Of course, I am still just a voodoo programmer, throwing flags and 
variables around without ever being totally sure what I am doing, so it 
could be I missed something important alongh the way!

[Please note that the OPT_CFLAGS above was hand-coded into 'configure'. 
I forgot to remove it just now, and I can't exactly remember what was 
there before, anyway ;-) But curiously, I don't see any sign of 
--enable-optimize=pentium4 anywhere here, nor in the output of 'make'!]

cheers,
