There are several additional options you may use on the configure command line when compiling gawk from scratch, including:
gawk. The --lint and --lint-old options (see Options) are accepted, but silently do nothing. Similarly, setting the
LINTvariable (see User-modified) has no effect on the running awk program.
When used with GCC's automatic dead-code-elimination, this option cuts almost 200K bytes off the size of the gawk executable on GNU/Linux x86 systems. Results on other systems and with other compilers are likely to vary. Using this option may bring you some slight performance improvement.
Using this option will cause some of the tests in the test suite to fail. This option may be removed at a later date.

Use the command ‘./configure --help’ to see the full list of options that configure supplies.
