With this option, on a typical 32-bit host, Emacs integers have 62 bits instead of 30. +Use --enable-gcc-warnings to enable compile-time checks that warn +about possibly-questionable C code. This is intended for developers +and is useful with GNU-compatible compilers. On a recent GNU system +there should be no warnings; on older and on non-GNU systems the +generated warnings may still be useful. + The `--prefix=PREFIXDIR' option specifies where the installation process should put emacs and its data files. This defaults to `/usr/local'. - Emacs (and the other utilities users run) go in PREFIXDIR/bin -- cgit v1.2.3
