[Boost-users] [shmem] error: constant is too large for long type

Hi all,

I try to port my application to windows and use mingw 3.4.2 (32 bit 
machine). I get the following error at compilation time and I'm not 
sure, is that a misconfiguration or bug?

./boost/shmem/sync/xtime.hpp: In function `int 
boost::shmem::xtime_get(boost::shmem::xtime*, int)':
./boost/shmem/sync/xtime.hpp:89: error: integer constant is too large 
for "long" type

The variable which should take this big decimal number 
(116444736000000000 -> exactly 32 bit) in line 89 is from type uint64_t 
and should have 64 bit unsigned. But that isn't so, it's just only 
long=int type (31 bit). If I look to the definition from uint64_t 
(boost/cstdint.hpp), there are much possibilities. With the GNU compiler 
it should be used the unsigned long long type as uint64_t and that are 
64 bits. In worst case it should be used a 32 bit unsigned long type. 
Why I've only a long type?

Thank you very much for reply, Sascha
