The following packages are needed by maintainers for using 'gnulib-tool'. In general, Gnulib prefers the latest stable version of each package, but in some cases it also supports older versions; this caters to commonly-used software distributions that may lag behind the latest stable package. Support for older versions is not guaranteed, though, and the version numbers in the following list may be incremented at any time. * A C runtime, compiler, linker, etc. + Mandatory. Using the platform's native 'cc' gives good portability exposure, but you can also use GCC 3.1 or newer. + GCC Homepage: https://gcc.gnu.org/ + Download: https://ftp.gnu.org/gnu/gcc/ * A 'make' utility. + Mandatory.
