Re: gawk: Internal Error

[Lakshmankumar Mukkavilli]

Thanks. I got the 3.1.0 version and the problem does not happen. But there
is a new issue. I am seeing a lot of new warnings about escape sequences
like

myprog1.awk:123: warning: escape sequence `\}' treated as plain `}'
myprog2.awk:194: warning: escape sequence `\$' treated as plain `$'
myprog3.awk:104: warning: escape sequence `\{' treated as plain `{'
myprog3.awk:105: warning: escape sequence `\}' treated as plain `}'
myprog3.awk:116: warning: escape sequence `\}' treated as plain `}'
myprog3.awk:125: warning: escape sequence `\$' treated as plain `$'

Is there a way to supress these kinds of messages. Looking  at the
documentation I did not see any. We dont like to change the source files.
These warnings are confusing the users and breaking the builds.
