Build issue with GCC on FreeBSD

To build with GCC on FreeBSD, change your `build_freebsd_x86_64` on `ecode-nightly.yml`: - To also install the package `gcc` - `CC=/usr/local/bin/gcc` and `CXX=/usr/local/bin/g++` The GCC package on FreeBSD is currently GCC 13.5 The error message I'm currently see: ``` In file included from ../../src/tools/ecode/ecode.hpp:10, from ../../src/tools/ecode/appconfig.cpp:2: ../../src/tools/ecode/plugins/plugincontextprovider.hpp:55:7: error: redefinition of 'class ecode::PluginContextProvider' 55 | class PluginContextProvider { | ^~~~~~~~~~~~~~~~~~~~~ In file included from ../../src/tools/ecode/plugins/pluginmanager.hpp:6, from ../../src/tools/ecode/projectdirectorytree.hpp:5, from ../../src/tools/ecode/filesystemlistener.hpp:4, from ../../src/tools/ecode/ecode.hpp:7: ../../src/tools/ecode/plugins/plugincontextprovider.hpp:55:7: note: previous definition of 'class ecode::PluginContextProvider' 55 | class PluginContextProvider { | ^~~~~~~~~~~~~~~~~~~~~ bus.cpp busprocess.cpp gmake[1]: *** [ecode.make:316: ../../obj/bsd/x86_64/release/ecode/appconfig.o] Error 1 gmake[1]: *** Waiting for unfinished jobs.... gmake: *** [Makefile:636: ecode] Error 2 ``` It's weird that this doesn't happen with GCC on other platforms. The GCC you are using on Linux seems to be also GCC 13. `plugincontextprovider.hpp` has `#pragma once`, so everything should be fine. I have no idea why this is happening.
