Some checks failed
buildbot / buildbot (push) Has been cancelled
For certain compilers we embed the compiler version used to build nginx in the binary, retrievable via 'nginx -V', e.g. $ ./objs/nginx -V ... built by gcc 15.2.1 20250808 (Red Hat 15.2.1-1) (GCC) ... However if the CFLAGS environment variable is set this would be omitted. This is due to the compiler specific auto/cc files not being run when the CFLAGS environment variable is set, this is so entities can set their own compiler flags, and thus the NGX_COMPILER variable isn't set. Nonetheless it is a useful thing to have so re-work the auto scripts to move the version gathering out of the individual auto/cc/$NGX_CC_NAME files and merge them into auto/cc/name.
