#870 Add compiler id to Help -> About dialog

[LETARTARE]

Added the 'gcc' compiler used in the 'About' window.

[Teodor Petrov]

This patch is not 100%, because it doesn't detect if clang is used as compiler.

[LETARTARE]

In 'StartHerePage::StartHerePage(...)' : no 'clang' detection, only 'GCC'
Here is a simplistic version of 'clang' detection since compiler
I can not check the 'clang' part.

[Teodor Petrov]

This doesn't work. Clang presents itself as GCC. So it defines the GNUC define. :(

For the start page, probably it is better to unify those so they are done in a single place.

[LETARTARE]

It was my goal, but I do not know how to do better !

May be I missed something, but what about this?:

#if defined (__clang__)
    + _T(" - clang ")  + (wxString()<< __clang_major__
    + _T(".") + (wxString()<< __clang_minor__)
    + _T(".") + (wxString()<< __clang_patchlevel__)
#elif defined (__GNUC__)
    + _T(" - gcc ") + (wxString()<< __GNUC__)
    + _T(".") + (wxString()<< __GNUC_MINOR__)
    + _T(".") + (wxString()<< __GNUC_PATCHLEVEL__)
#endif

[Teodor Petrov]

Yes, this would probably work correctly.

[LETARTARE]

     Or again, which allows to add other GNUC compilers
                #ifdef __GNUC__
                                  #ifdef __clang__
                                        + _T(" - clang ")  + (wxString()<< __clang_major__
                                        + _T(".") + (wxString()<< __clang_minor__)
                                        + _T(".") + (wxString()<< __clang_patchlevel__)
                                    #else
                                        + _T(" - gcc ") + (wxString()<< __GNUC__)
                                        + _T(".") + (wxString()<< __GNUC_MINOR__)
                                        + _T(".") + (wxString()<< __GNUC_PATCHLEVEL__)
                                    #endif
                     #endif

Applied (modified) in SVN. Thank you!

[Miguel Gimenez]

The check order in the applied patch must be changed, because (as Teodor Petrov said) Clang defines __GNUC__
