Here is a report on compiling rational_example.cpp with Metrowerks
* #ifdef _MSC_VER is true, causing the Microsoft hacks to be
invoked, which of course fail with the more standards conforming CW
Several companies (Metrowerks, Intel, at least, probably more)
predefine _MSC_VER in an attempt to be compatible. Sigh.
* After commenting out the above, tried again and got:
Error : illegal access to protected/private member
(instantiating: 'boost::?$abs_at_H(const boost::rational<int> &)')
rational.hpp line 299 return rational<IntType>(abs(r.num),
(r.num) was underlined.
* After commenting out "private:" to hack around the above, the
compile was clean.
* Ran apparently OK with the output:
2 * 2147483647/2=2147483647 (rational: 2147483647/1)
pi = 3.14286 (nearly)
Sorry; I was pressed for time and did nothing more.
Hope the above helps.
