SUMMARY

To compile a file with any of the Microsoft language compilers listed above, list any appropriate compiler option switches on the command line before the names of the source files to which the options apply.

MORE INFORMATION

When you are using a Microsoft 16-bit C/C++ compiler, if you specify an option at the end of the command line, after the names of all the files, the compiler does not generate any warnings or errors -- it simply ignores the option because no source file follows for the option to apply to. In a few cases, a trailing option causes an error because the option conflicts with a previously specified option.

Microsoft 32-bit C/C++ compiler supports placing option switches after the names of source files. If a compiler command line specifies more than one source code file, specified options apply to all files regardless of the position of the option switch relative to the source filename. However, if the -link switch is to be used, it must occur after all source filenames and compiler switches.
