    headers
  * linux/.cvsignore: added ioctdefs.h and ioctls.h which are generated
    by the new ioctlent.sh

    ioctlent.sh no longer supplies the others

2001-03-08  John Hughes <[e-mail]>

    pretend they have names ending with "?" so that -e trace=stat (for

2001-03-07  John Hughes <[e-mail]>

  * defs.h: add ALIGN64 macro to cope with FreeBSD's strange insistence
    on alignment for off_t (64 bit) arguments.  Also simplify get64 so
    we don't need to know endianness of long long.
  * file.c: FreeBSD now uses 64 bit versions of lseek, truncate,
    ftruncate, allows reduction in numvber of horrid #if's

    merge Harald B鰄me's solaris patches (_LFS64_LARGEFILE and kernel aio
    mostly).

    to adjust bsp by moving it back by the size of the active frame
    before using it.
