After some testing it seems that -m32mscoff and -m64 both build correctly so its related to 32bit dmd on windows

'lseek' is a posix function. There's a version/#define somewhere that's missing, maybe in the C binding, because under Windows lseek is 'SetFilePointer'. But I'm not able to find it... :/

I searched the function "__lseek64" under /usr/include/dmd" with
"grep -R __lseek64", but nothing is found. I work on Linux
64-bit. So, I guess it is either Windows related, or 32bit dmd
related. "lseek64" is found in "unistd.d", but this doesn't solve
any problem.
