 Ok, but there is also the main problem:
 why not to change also ::acosl into std::acosl (and this change
 for few other math functions) ?
 
 This should correct the error:
  /usr/local/include/g++-v3/bits/std_cmath.h: In function `long double 
                   foo::std::acos(long double)':
                   /usr/local/include/g++-v3/bits/std_cmath.h:121: `::acosl'
 	          undeclared (first use here)
