Comment:

 this patch ([79337]) breaks mutex, using Intel Composer XE 2013.

 semicolon is the comment for MASM format.

 icl.exe compiles
 {{{
 __asm {
     mov eax,bit; mov edx,x; lock bts [edx],eax; setc al; mov ret, al
 };
 }}}
 to
 {{{
 ; Begin ASM
   00004 8b 45 0c         mov eax, DWORD PTR [12+ebp]
 ;C:\boost-1.51.0\boost/thread/win32/thread_primitives.hpp:354.21
 ; End ASM
 }}}

 , and this code is meaningless.
