std::limits compile errors with boost
Anyone has seen this?: In file included from ../include/boost/lockfree/detail/freelist.hpp:12, from ../include/boost/lockfree/queue.hpp:24, from test.cpp:2: /usr/local/powerpc-linux-gnu/include/c++/4.3.2/limits:287:22: error: macro "min" requires 2 arguments, but only 1 given Thanks
It looks like the min and max macros are defined for your project. I don't know how you do it in gcc, but in Visual Studio you define NOMINMAX to disable those. This is necessary because <limits> won't work otherwise. Best regards, M.

You need to ensure that *all* references to min and max are enclosed in brackets
for example
(std::numeric_limits<FPT>::max)();

says:
* Make sure your code compiles in the presence of the min() and max()
macros. Some platform headers define min() and max() macros which cause some
common C++ constructs to fail to compile. Some simple tricks can protect your
code from inappropriate macro substitution:
* If you want to call std::min() or std::max():
* If you do not require argument-dependent look-up, use (std::min)(a,b).
*
* If you do require argument-dependent look-up, you should:
*
* #include

The error was in a standard header (limits) so that isn't really possible. To understand the issue we need a minimal example of code which triggers this error, so that we can find out where the min macro was defined. If it's specific to g++ 4.3 or powerpc linux, it might be tricky as neither is widely used, but maybe someone might know something.
