12956,Already defined errors in VS2008 ARM because of enable_if_c,Vyacheslav Lanovets <vyacheslav@…>,John Maddock,"Solution:Use enable_if instead of enable_if_c where possible.

To see the problem, it's enough to include cpp_bin_float.hpp.


Win32 compiler in VS2008 sp1 compiles it normally. But ARMV4I clarm compiler in the same installation with Widows Mobile 6 SDK - does not. While there are many Windows CE systems out there, MS stopped producing compilers for it long time ago. Everybody is stuck with VS2008.

Use of ""::value"" as argument makes it optimistically bring the function into scope. And later it complaints about redefinition.


Replacing enable_if_c with enable_if wherever possible in cpp_bin_float.hpp apparently forces compiler to perform substitution, and it fails and SFINAE works.
