SVR uses GNU configure to select options, and, for the most part, automake to process them. Therefore, most options will be standard for GNU programs. I have not fully tested standards-conformance beyond the options in the table below. The --enable-FOO switches have corresponding --disable-FOO switches, which are equivalent to --enable-FOO=no; similarly with --with-FOO and --without-FOO.

option	default	description
--prefix	/usr/local	Where to install
--enable-warnings	yes	Whether gcc should treat warnings as errors
--enable-expensive-assertions	no	For debugging: enable extremely expensive assertions
--with-wordsize=[no|32|64]	no	Specify the wordsize to use. Error if not supported.
--with-fastest-gcc-flags	no	Tries to pass -O3 -fomit-frame-pointer -march=native -mtune=native -DNDEBUG. Note: make check will fail under these options unless --disable-warnings is also provided.
--with-assertions	no	Does not let --with-fastest-gcc-flags pass -DNDEBUG.
