Preprocessor files / temporary compile files not saved

[madworm]

I started with a clean 1.0.2 installation, wiped the preferences.txt file as well. Enabled "preproc.save_build_files=true", but all that remains in /tmp/buildXXXXX is the .cpp and .cpp.d file. I would like to see the code after it has gone through the preprocessor with all text replacements done to debug compilation errors.

I think "-save-temps" would be nice to have.

The /tmp/buildXXXXX.cpp file is the result of the preprocessing done by the IDE.
Related to preprocessing, you may want to give a spin to this version of the IDE bundled with a new preprocessor

New preprocessor tracked at #2636. Builds for testing it are available

New preprocessor available in nightly builds. Temporary files are preserved when using CLI and specifying --preserve-temp-files. See https://github.com/arduino/Arduino/blob/master/build/shared/manpage.adoc
