I successfully built 1.4.4 on an i386 GNU/Linux Fedora 4 system, but when
I attempt the same build on my x86_64 GNU/Linux CentOS 4.3(RHEL clone), I
get the error shown below.

Just for fun I ran the savage benchmark on my Mega16 at 6MHz. I
attempted to use double precision everywhere. (I say attempted because
I'm no expert at this.)
double d = 1;
uint16_t i;
for (i=1; i2500; i++)
{
d = tan(atan(exp(log(sqrt(d*d) + 1;
}
Here are the
Just as a point of reference:
Execution times for the aforementioned benchmark
386 (with 387 co-processor) @ 33MHz
.67s
486DX2 66MHz
.121s
Considering that the AVR is 8bit and has no hardware floating point, being
only 12x slower than the 386 is impressive especially considering it runs
at 1/5

A further test reveals (to me) that sizeof(float) == sizeof(double) == 4.

Under Gentoo Linux we also put the gcc files under /usr/lib/

Which is fairly well in line with the 32-bit float results
from the i386.
Is there a way to have sizeof(double) == 8?
Currently not. Volunteers are needed to hammer all this
out, in

The same calculations are definitely performed for both. However,

Both FreeBSD and Gentoo use portage, correct? Where do I look to
