The order of compilation when the C preprocessor runs first

When a user chooses to run the C preprocessor on the source file before the preprocessor, the file undergoes the following order of compilation.

1. The eprotect utility runs on the source file to protect all SQL keywords against interpretation by the C preprocessor.
2. The C preprocessor runs on the source file.
3. The eprotect utility runs on the output of the C preprocessor with the -u mode to remove SQL keyword protection.
4. The preprocessor runs on the output of the C preprocessor, which no longer has any SQL keyword protection.
5. The output of the preprocessor undergoes compilation and linking by the C compiler and linker to produce an executable file.
