What C compilers are available?

Almost all of our systems have a vendor-provided traditional C compiler named cc, and a 1989 ISO Standard C compiler named c89. Sun Solaris 10, and some recent GNU/Linux systems, also have a 1999 ISO Standard C compiler named c99. However, there are still some deficiencies and omissions of the GNU compiler in conformance to the 1999 ISO Standard, whereas the Sun compiler is believed to be fully conformant. All of our systems also have the GNU C compiler, named gcc. On GNU/Linux, FreeBSD, Mac OS X, OpenBSD, and NetBSD systems, the native compiler cc is just a version of the GNU C compiler, and usually older than the gcc that is installed in /usr/local/bin. The GNU C compiler is normally version 3.x.y or, on very old systems, 2.95.3. However, several systems also have a newer version named gcc4.
