* 3.0: gaol can now be safely mixed with programs or libraries that manipulate the control word
	of the fpu by using the --enable-preserve-rounding option.
* 1.1.0: correction of a bug that affected cos() and sin() function, whereby two calls in a row
	would lead to a wrong result for the second one.
* 0.0.3: added support for PowerPC under MacOs X. This is still experimental since I do not have 
	a powerpc to test with.
