9392	BOOST_NOINLINE NVCC in __HOST__	a.huebl@…	John Maddock	"

I am compiling with '''gcc 4.6.2''' and CUDA ('''nvcc 5.0''', V0.2.1221)
causing an:

{{{
include/boost/assert.hpp:102:47: Error: »noinline« was not defined in
this scope
}}}

if I do '''not''' override with

{{{
-DBOOST_NOINLINE='__attribute__ ((noinline))'
}}}

The problem resides at ''boost/config/suffix.hpp''.

Affected files (using):
  - ''include/boost/assert.hpp''
  - ''include/boost/log/detail/spin_mutex.hpp''

That's strange, since it works in code not included in {{{__host__}}} calls.

Example to reproduce the problem:
{{{
#include <stdlib.h>     /* srand, rand */
#include <time.h>       /* time */

#include <boost/assert.hpp>

__host__ void abc()
{
   int i = 3;
   BOOST_ASSERT_MSG( i%2 == 0, ""MYMESSAGE"" );
}

int main()
{
  srand (time(NULL));
  int i = rand() % 10 + 1;

  BOOST_ASSERT_MSG( i%2 == 0, ""MYMESSAGE"" );

  return 0;
}
}}}

Compile with:
  - {{{nvcc main.cu}}}
  - {{{nvcc -DBOOST_NOINLINE='__attribute__ ((noinline))' main.cu}}}
