Some users build FreeBSD as non-root in Perforce workspaces. By default, Perforce sets files read-only unless they're explicitly being edited. As a result, the -f argument must be used to cp in order to override the read-only flag when copying source files to object directories. Bare use of 'cp' should be avoided in the future. Update all current users of 'cp' in the src tree. Reviewed by: emaste MFC after: 1 week Sponsored by: Spectra Logic

# By default, flex will be configured to generate 8-bit scanners only if the
|
|
# -8 flag is given. If you want it to always generate 8-bit scanners, add
|
|
# "-DDEFAULT_CSIZE=256" to CFLAGS. Note that doing so will double the size
|
|
# of all uncompressed scanners.
|
|
#
|
|
# Bootstrapping of lex is handled automatically.
|
|
# Also note that flex.skel no longer gets installed.
