freebsd-dev/lib/libc/Makefile
Rui Paulo 271e7c594b Disable all warnings when building gdtoa. This allows building libc with
clang.
The general idea is that the vendor will not accept our compilation
patches and so disabling the warnings is the best way to go as it makes
future imports bearable.

# All library objects contain FreeBSD revision strings by default; they may be
# excluded as a space-saving measure. To produce a library that does
# not contain these strings, add -DSTRIP_FBSDID (see <sys/cdefs.h>) to CFLAGS
# below. Note: there are no IDs for syscall stubs whose sources are generated.
# To include legacy CSRG sccsid strings, add -DLIBC_SCCS and -DSYSLIBC_SCCS
# to CFLAGS below. -DSYSLIBC_SCCS affects just the system call stubs.
