While trying to compile tango with dmd 1.046, I ran into the a problem with the
di-header generated for atomic.d. A reduced version that reproduces the bug in
dmd 2.032 aswell is

test.d:

int foo(int function() fn)
{
    return fn();
}

int bar(T)()
{
    return foo(function int (){ return 0; });
}

>dmd -c -H test.d

>dmd -c test.di
test.di(10): found 'function' when expecting '.' following 'int'
test.di(10): found '(' when expecting identifier following 'int.'
test.di(11): found '{' when expecting ';' following 'return statement'
test.di(14): Declaration expected, not ')'
test.di(16): unrecognized declaration

This is caused by a wrong function literal being generated into the di-file:

// D import file generated from 'test.d'
int foo(int function() fn)
{
return fn();
}
template bar(T)
{
int bar()
{
return foo(int function()
{
return 0;
}
);
}
}

Note the difference "foo(int function()..." and "foo(function int ()...".
