When compiling on DECstation running Ultrix 4.0 a command 'cc -c -O
|
||
|
|
regex.c' is causing an infinite loop in an optimizer. Other sources
|
||
|
|
compile fine with -O flag. If you are going to use this flag either
|
||
|
|
add a special rule to Makefile for a compilation of regex.c, or issue
|
||
|
|
'cc -c regex.c' before hitting 'make'.

Just fyi -- it passes tests with flying colors under Ultrix 4.2. The
|
||
|
|
README.ultrix file applies more than ever. You might want to add
|
||
|
|
these paragraphs to it:
|
||
|
|
|
||
|
|
As of Ultrix 4.2 the optimise works for regex.c, but you must give an
|
||
|
|
additional switch to get everything optimised. Using '-Olimit 1500'
|
||
|
|
does the job. Without the switch gawk will compile and run correctly,
|
||
|
|
but you will get complaints about lost optimisations in builtin.c,
|
||
|
|
awk.tab.c and regex.c.

On Decstations using Ultrix 4.3, the tweakfld test case will fail. It
|
||
|
|
appears that routines in the math library return very small but non-zero
|
||
|
|
numbers in cases where most other systems return zero.
