Here is my question:

|> On my machine, it has /usr/5bin/cc, /usr/lang/acc, /usr/ucb/cc,

-------------------------------------
Here are the consoliated answers:
--- /usr/5bin/cc is the systemV compliant cc -- it just uses /usr/5include
header files instead of /usr/include.
--- /usr/ucb/cc is the standard, bundled c compiler.
--- You need to buy an unbundeled SunSOFT C 1.0 or 2.0 Compiler or use GNU gcc which is
certainly ANSI compliant, however unsupported.
--- The bundled compiler is the outdated K&R version compiler inherited from the old UNIX days.
--- Sun has decided to unbundle the new compiler and sell it as a separate product.
--- /usr/ucb/cc is the "normal" bundled C compiler. The
version in /usr/5bin and /usr/xpg2bin is the System V version of the
bundled C compiler. The manual page also says:
/usr/xpg2bin/cc is a shell script that should be used to
compile X/Open compliant applications. /usr/5bin/cc and
/usr/xpg2bin/cc accept the same arguments and options as cc.
/usr/xpg2bin/cc searches /usr/xpg2include for #include files
before /usr/include, and specifies /usr/xpg2lib/libxpg.a as
an additional static library of object-library routines.
These compilers are called "bundled", because they are part of the
SunOS distribution.
--- /usr/lang/acc is Sun's unbundled ANSI C compiler. As it's unbundled
you had to order and pay it separately from the OS.
