>Release: 1.3b7
>Environment:
At least UTS 2.1.2 and IRIX 5.3
>Description:
There's an awk script in the "configure" program that tries to break up
sed scripts to get around braindead seds. Unfortunately, it breaks on
braindead awks!
>How-To-Repeat:
Extract the awk script out of configure and try it on some scratch files.
>Fix:
On IRIX 5.3, it is sufficient to change the input file from being sent to it
via standard input to instead be a parameter at the end of the awk command line.
UTS 2.1.2, however, has another problem in that the >$file overwrites the file
on every line so each file only contains the last line. The only solution I
could think of was to use nawk if it is available. This fixes the IRIX 5.3
problem too. A patch is below. There are many other problems specific to
UTS 2.1.2 only but I am going to submit those in a separate report.
