Hello,
Here is a sample script to invoke awk:
$ cat ./gawk_error.sh
#!/bin/sh
echo "This:is:a:colon:separated:line:%%%:" | awk '{
gsub("\\%", "%25", $0);
gsub("\\:", "%3A", $0);
print
}'
----
If I invoke it with gawk 5.0.1-1, I see warnings as below:
$ uname -a
CYGWIN_NT-10.0 MyPC 3.0.7(0.338/5/3) 2019-04-30 18:08 x86_64 Cygwin
$ awk -V

$ ./gawk_error.sh
awk: cmd. line:2: (FILENAME=- FNR=1) warning: regexp escape sequence `\%'

awk: cmd. line:3: (FILENAME=- FNR=1) warning: regexp escape sequence `\:'
is not a known regexp operator

This script runs without any warnings with older versions of gawk:
$ awk -V
GNU Awk 4.2.1, API: 2.0 (GNU MPFR 4.0.1, GNU MP 6.1.2)
Copyright (C) 1989, 1991-2018 Free Software Foundation.
...
$ ./gawk_error.sh
This%3Ais%3Aa%3Acolon%3Aseparated%3Aline%3A%25%25%25%3A
----
The script runs without any warnings on Linux and other Unix variants.
Is this a regression in gawk 5.0.1-1 on Cygwin ?
Thanks in advance.
