GCC 12.5 Release Candidate available from gcc.gnu.org
The first release candidate for GCC 12.5 is available from https://gcc.gnu.org/pub/gcc/snapshots/12.5.0-RC-20250704/ ftp://gcc.gnu.org/pub/gcc/snapshots/12.5.0-RC-20250704/ and shortly its mirrors. It has been generated from git commit r12-11250-gb71ac987cd1499. I have so far bootstrapped and tested the release candidate on x86_64-linux. Please test it and report any issues to bugzilla. If all goes well, we'd like to release 12.5 on Friday, Jul 11th and close the branch.

In this case you're compiling something for the host platform and CXXFLAGS is the appropriate variable. You need to pass the various FLAGS on the 'make' command line instead of the 'configure' command line. -- Eric Botcazou

And therein lies the rub. With the COBOL front end, we recently hit a situation where we inadvertently used a C++17 feature that resulted in a compilation failure using GCC-9. So, I want to be able to set "-std=c++14" when compiling the COBOL front end. But when I set CXXFLAGS="-std=c++14", that causes the compilation of libcody to fail. It insists on the standard being exactly C++11. I suppose the proper question is, "How do I set compilation flags for just the gcc/cobol front end compilation?" Best regards, and thanks very much for getting back to me on this...

Compiler optimization help
Hello, I'm looking to contribute to the project, hoping to implement the compiler optimization specified in: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63164. Would appreciate any help/tips regarding what files I should look at to start working towards implementing something like this, cheers!
