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.
well, it seems that my changes to the configure script haven't reached you ... are you on the recent cvs (devel_0_37)???
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.
btw, there is an explanation on the denormal issue at: http://www.musicdsp.org/phpWiki/index.php/What%20is%20a%20denormal%20number%...
