accepts several types of arguments:
Arguments whose names end with `.c' are taken to be
C source programs; they are compiled, and
each object program is left on the file
whose name is that of the source with `.o' substituted
The `.o' file is normally deleted, however, if a single
C program is compiled and loaded all at one go.
arguments whose names end with `.s' are taken to be assembly source programs
and are assembled, producing a `.o' file.
The following options are interpreted by
Suppress the loading phase of the compilation, and force
an object file to be produced even if only one program is compiled.
Have the compiler produce additional symbol table information
Have the compiler produce additional symbol table information

Suppress warning diagnostics.
Arrange for the compiler to produce code
which counts the number of times each routine is called.
If loading takes place, replace the standard startup
routine by one which automatically calls
at the start and arranges to write out a
file at normal termination of execution of the object program.
An execution profile can then be generated by
Causes the compiler to produce counting code in the manner of
but invokes a run-time recording mechanism that keeps more
extensive statistics and produces a
file at normal termination.
Also, a profiling library is searched, in lieu of the standard C library.
An execution profile can then be generated by use of
making initialized variables shared and read-only.
Compile the named C programs, and leave the
assembler-language output on corresponding files suffixed `.s'.
Run only the macro preprocessor

Name the final output file
If this option is used the file `a.out' will be left undisturbed.
If no definition is given, the name is defined as "1".
Remove any initial definition of

Use an alternate compiler which does not convert expressions involving
only floats to double. This does not conform to the standard which states
that all intermediate results should be converted to double but does
provide a speed improvement for programs which don't require full double
precision. This option also makes
variables work appropriately.
