47 This is the name of the C language compiler as required by the

57 object files that are produced.

87 option may be specified more than once.
89 Copy C-language source files to the standard output, expanding all
90 preprocessor directives; no compilation will be performed.
92 Produce symbolic information in the object or executable files.
94 Change the algorithm for searching for headers whose names are not
95 absolute pathnames to look in the directory named by the
97 pathname before looking in the usual places.
99 names are enclosed in double-quotes
101 will be searched for first
102 in the directory of the file with the
107 options, and last in the usual places.
108 For headers whose names are enclosed in angle brackets
111 will be searched for only in directories named in
113 options and then in the usual places.
116 options shall be searched in the order specified.

155 An operand is either in the form of a pathname or the form
158 At least one operand of the pathname form needs to be specified.
159 Supported operands are of the form:
160 .Bl -tag -offset indent -width ".Fl l Ar library"
162 A C-language source file to be compiled and optionally linked.
163 The operand must be of this form if the
167 A library of object files, as produced by

171 An object file produced by

177 A library will be searched when its name is encountered, so the
