This should be fixed in commit 41ee91c64f47faaa by skipping the alignment of the data area, if PAGE_SIZE is not defined. An alternative approach would have been to define PAGE_SIZE to a sane default value of 4096 (as used on most current architectures by default), if not set in the build environment. If there is consensus that this would be more appropriate (since it matches what the man page says), I'd revert the latest commit and instead of it commit the following change: index 1bca560a59e1..c4f18a28ec39 100644 --- a/sbin/newfs_msdos/mkfs_msdos.c +++ b/sbin/newfs_msdos/mkfs_msdos.c @@ -55,6 +55,10 @@ #include "mkfs_msdos.h" +#ifndef PAGE_SIZE +#define PAGE_SIZE 4096 +#endif + #define MAXU16 0xffff /* maximum unsigned 16-bit quantity */ #define BPN 4 /* bits per nibble */ #define NPB 2 /* nibbles per byte */ Regards, STefan
