Comment 2 for bug 1714265

Yes, the preprocessing variants may be very different from different compiler suites and/or distributions. Generic cpp behaves very different from gcc-cpp, let alone ifort pre-processor.

I am very positive about the upgrade of the codes to a common standard. However, the capitalisation I have found very useful from time to time. I.e. a non-capitalised source does not get preprocessed (as is commonly used in compilers).

If one retains the capitalisation one can immediately see from the file name whether it gets preprocessed, or not. So I would probably like to retain this form. If a file should be pre-processed then it has to change name.

Again, I think you should decide. :)
