--- Comment #6 from Jignesh <j130496 at live dot co.uk> --- As per guidance somewhere I will need to change configure script CFLAGS and some other flag to point to new glibc. Can you please guide what and where I will have to change to recompile gcc developmental version successfully. My new libraries of glibc 2.33.9000 are at /usr/local/lib. Thank you.
