| 4 | Subject: [PATCH] Enable 64bit off_t |
| 5 | |
| 6 | Ensure that off_t is always 64-bit by specifying -D_LARGEFILE_SOURCE |
| 7 | -D_FILE_OFFSET_BITS=64 this will ensure that normal lseek() function is |
| 8 | same as lseek64 |
| 9 | |
| 10 | This helps compiling on latest musl where lseek64 and friends are not |
| 11 | available |
