--- Comment #3 from kargls at comcast dot net --- So, in my testing I use an 80-column wide xterm. The warning I see is Warning: The Hollerith constant at (1) is truncated in conversion to 'INTEGER(4' [-Wcharacter-truncation] The last parenthesis is gone. If I resize the xterm to 81 columns, I see Warning: The Hollerith constant at (1) is truncated in conversion to 'INTEGER(4)' [-Wcharacter-truncation] which magically produces the ')' character.
