[openssh.git] / ChangeLog

20040408
 - (dtucker) [loginrec.c] Use UT_LINESIZE if available, prevents truncating
   pty name on Linux 2.6.x systems.  Patch from jpe at eisenmenger.org.
 - (bal) [monitor.c monitor_wrap.c] Second try.  Put the zlib.h headers
   back and #undef TARGET_OS_MAC instead.  (Bug report pending with Apple)
 - (dtucker) [defines.h loginrec.c] Define UT_LINESIZE if not defined and
   simplify loginrec.c.  ok tim@

   developers any more. (Patch based on Apple tree)
 - (bal) [monitor.c monitor_wrap.c] monitor_wrap.c] moved zlib.h higher since 
   krb5 on MacOS/X conflicts.  There may be a better solution, but this will 
   work for now.
