Mixing Qt and boost causes compilation error with "check" keyword - qt

Question

I am using Qt in a project and am now trying to include another project that uses boost.
I have added no_keywords to my config in the qt project file to avoid collision between the signal and slots functionality that is present in boost and Qt. But now I get a compilation error which seems to stem from double definition of a function called "check". Is there some way to avoid this?
An example is has_postfix_operator.hpp (line 141):
static ::boost::type_traits::yes_type check(has_operator); // this version is preferred when operator exists
Apparently there is a "check" defined in Qt.
I'm using Qt4.7 and boost 1.48. Running MacOSX 10.6.8

You should also look at /usr/include/AssertMacros.h, which defines a macro named "check" - that could be the cause of your problem.
To check this, add -d __ASSERT_MACROS_DEFINE_VERSIONS_WITHOUT_UNDERSCORES=0 to your compiler flags.
If that works, that was your problem.
Here's a comment from that file:
Prior to Mac OS X 10.6 the macro names used in this file conflicted
with some user code, including libraries in boost and the proposed C++
standards efforts, and there was no way for a client of this header to
resolve this conflict. Because of this, most of the macros have been
changed so that they are prefixed with
__ and contain at least one capital letter, which should alleviate the current and future conflicts. However, to allow current sources to
continue to compile, compatibility macros are defined at the end with
the old names. A tops script at the end of this file will convert
all of the old macro names used in a directory to the new names.
Clients are recommended to migrate over to these new macros as they
update their sources because a future release of Mac OS X will remove
the old macro definitions ( without the double-underscore prefix ).
Clients who want to compile without the old macro definitions can
define the macro
__ASSERT_MACROS_DEFINE_VERSIONS_WITHOUT_UNDERSCORES to 0 before this file is included.
