The following sed command
sed -n -e "s|.*typedef  *\(.*\) X*clock_t *;.*|\1|w TMP" < dummy.out
with the following dummy.out:
typedef long  clock_t;  
typedef long  time_t;   

should create a "TMP" file that contains "long".  Instead, sed 1.09
creates an empty "TMP" file.

This is for sed version 1.09 compiled with GCC version 2.2.2 on a Sun
Sparcstation ELC running SunOS 4.1.1.

The problem is that sed never closes the files it opens, so buffered
writes don't get written.  Following is a sample patch to sed.c.
