+1 GCC
+ The GCC command invokes the GNU C compiler.
+
+      GCC file-spec
+
+2 Parameters
+
+ file-spec
+
+     A C source file.  If no input file extension is specified, GNU C 
+     assumes .C as the default extension.
+
+2 Qualifiers
+
+ GNU C command qualifiers modify the way the compiler handles the
+ compiliation.
+
+ The following is the list of available qualifiers for GNU C:
+
+
+      /CC1_OPTIONS=(option [,option...]])
+
+      /DEBUG
+
+      /DEFINE=(identifier[=definition][,...])
+
+      /INCLUDE_DIRECTORY=(path [,path...]])
+
+      /MACHINE_CODE
+
+      /OPTIMIZE
+
+      /UNDEFINE=(identifier[,identifier,...])
+
+      /VERBOSE
+
+
+2 Linking
+
+ When linking programs compiled with GNU C, you should include the GNU
+ C library before the VAX C library.  For example,
+
+  LINK object-file,GNU_CC:[000000]GCCLIB/LIB,SYS$LIBRARY:VAXCRTL/LIB
+
+ You can also link your program with the shared VAX C library.  This
+ can reduce the size of the .EXE file, as well as make it smaller
+ when it's running.  For example,
+
+  $ LINK object-file, GNU_CC:[000000]GCCLIB/LIB,SYS$INPUT:/OPTIONS
+  SYS$SHARE:VAXCRTL/SHARE
+
+ (If you use the second example and type it in by hand, be sure to type
+  ^Z after the last carriage return)
+
+2 /DEBUG
+
+ /DEBUG includes additional information in the object file output so
+ that the program can be debugged with the VAX Symbolic Debugger.
+ This qualifier includes very little information, so using the
+ debugger is somewhat difficult.
+
+2 /DEFINE=(identifier[=definition][,...])
+
+ /DEFINE defines a string or macro ('definition') to be substituted 
+ for every occurrence of a given string ('identifier') in a program.
+ It is equivalent to the #define preprocessor directive.
+
+ All definitions and identifiers are converted to uppercase unless they
+ are in quotation marks.
+
+ The simple form of the /DEFINE qualifier,
+
+ /DEFINE=vms
+
+ results in a definition equivalent to the preprocessor directive
+
+ #define VMS 1
+
+ You must enclose macro definitions in quotation marks, as in this
+ example:
+
+ /DEFINE="C(x)=((x) & 0xff)"
+
+ This definition is the same as the preprocessor definition
+
+ #define C(x) ((x) & 0xff)
+
+ If more than one /DEFINE is present on the GCC command line, only
+ the last /DEFINE is used.
+
+ If both /DEFINE and /UNDEFINE are present on a command line, /DEFINE
+ is evaluated before /UNDEFINE
+
+2 /INCLUDE_DIRECTORY=(path [,path...])
+
+ The /INCLUDE_DIRECTORY qualifier provides additional directories to
+ search for user-defined include files.  'path' can be either a 
+ logical name or a directory specification.
+
+ There are two forms for specifying include files - #include "file-spec"
+ and #include <file-spec>.  For the #include "file-spec" form, the search
+ order is:
+
+ 1.  The directory containing the source file.
+
+ 2.  The directories in the /INCLUDE qualifier (if any).
+
+ 3.  The directory (or directories) specified in the logical name
+     GNU_CC_INCLUDE.
+
+ 4.  The directory (or directories) specified in the logical name
+     SYS$LIBRARY.
+
+ For the #include <file-spec> form, the search order is:
+
+ 1.  The directories specified in the /INCLUDE qualifier (if any).
+
+ 2.  The directory (or directories) specified in the logical name
+     GNU_CC_INCLUDE.
+
+ 3.  The directory (or directories) specified in the logical name
+     SYS$LIBRARY.
+
+2 /MACHINE_CODE
+
+ Tells GNU C to output the machine code generated by the compiler.  Note
+ that no object file is produced when /MACHINE_CODE is specified.  The
+ machine code is output to a file with the same name as the input file,
+ with the extension .S.
+
+2 /OPTIMIZE
+    /NOOPTIMIZE
+
+ Controls whether optimization is performed by the compiler.  By default,
+ optimization is on.  /NOOPTIMIZE turns optimization off.
+
+2 /UNDEFINE
+
+ /UNDEFINE cancels a macro definition.  Thus, it is the same as the
+ #undef preprocessor directive.
+
+ If more than one /UNDEFINE is present on the GCC command line, only
+ the last /UNDEFINE is used.
+
+ If both /DEFINE and /UNDEFINE are present on a command line, /DEFINE
+ is evaluated before /UNDEFINE
+
+2 /VERBOSE
+
+ Controls whether the user sees the invocation command strings for the
+ preprocessor, compiler, and assembler.  The compiler also outputs
+ some statistics on time spent in its various phases.
