Problem Description: 

1109242  bad code generated when addresses of two double arguments were involved
1112278  -O3  (reassoc phase) yields incorrect code for bit-field extraction


The currently released compilers have a minimum linger time of 15
minutes.  The linger time can be increased in the license options file,
but it cannot be decreased below 15 minutes.
 
This means that a license token will remain checked out for 15 minutes
after the compiler that checked it out has exited.  This is useful when
the same user is about to start another compile that can use the same
license, but it is inconvenient after one user is really finished with
the license and another user is waiting to use it.
 
---------------------
 
Installing this patch will reduce the minimum linger time from 15
minutes to 0.  If you use a linger time of 0, as soon as a compile
finishes, its license token will be returned to the pool of available
tokens.
 
SunPro recommends specifying a linger time of 5 minutes (300 seconds)
to improve performance and to avoid queueing to wait for a license in
the middle of a long make.  The linger value can be set in the license
options file.  For example, the line:
 
LINGER  sunpro.c        300
 
would set it to 5 minutes for SPARCompiler C.
 
The name of the license options file appears in the fourth field on the
DAEMON line in the license file (usually called license.dat) on your
license server.  See the SunPro Installation manual for details.
