That's probably the wrong way to do it, better
#define _LARGEFILE_SOURCE 1
#define _FILE_OFFSET_BITS 64
or the equivalent on the compiler and linker command lines - the
canonical way to obtain these flags would be to use getconf(1) to query
LFS_CFLAGS, LFS_LIBS, LFS_LDFLAGS.
This works at least on Solaris and Linux.
