OPT_DO_2COMP

This configuration parameter defines a list of options triggering ctc to execute the original compilation command first without modification.. After that, normal instrumentation processing is done.

Example:
OPT_DO_2COMP = /Fr,/FR
These options are Visual C++ (cl) options for generating source browsing files. For those files being meaningful they need to be generated during the compilation of the original source files, not during the compilation of the temporary instrumented files named by ctc. Doing a ctc-free compilation first generates these dependency files with their correct names.

This parameter may be used as a replacement of the explicit ctc option -2comp. With it, the double compilation is only done when needed.
