The source code line content, saved to improve error reporting, might
get truncated, as the current Bison source buffer is 8192 bytes long and
only 254 bytes (plus NUL-terminator) are reserved.
As the saved string is only used for improving error reports and source
lines longer than 254 character are quite uncommon, simply silence the
GCC warning.
