Okay. For what it's worth:
On 64-bit windows 7 I see what your friend sees, i.e., the full number gets
printed. I am using Ruben's 64-bit experimental std::thread 4.7 build:
C:\>gcc --version
gcc (GCC) 4.7.0 20110829 (experimental)
C:\>gcc -Wall -o printf_ll_test printf_ll_test.c
printf_ll_test.c: In function 'main':
printf_ll_test.c:10:1: warning: unknown conversion type character
'l' in format [-Wformat]
printf_ll_test.c:10:1: warning: too many arguments for format
[-Wformat-extra-args]
C:\>printf_ll_test
1125899906842749
The version of my msvcrt.dll is 7.0.7600.16385.
But we probably expected that since my os is newer rather than older.
Happy Hacking!
