# 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 CPPFLAGS.  Note that doing so will double the size
# of all uncompressed scanners.
# 
# If on your system you have trouble building flex due to 8-bit character
# problems, remove the -8 from FLEX_FLAGS and the "#define FLEX_8_BIT_CHARS"
# from the beginning of flexdef.h.
#
# To bootstrap lex, cp initscan.c to scan.c and run make.

Rework how MAKEVERBOSE operates: * Don't bother prefixing commands with a line of ${_MKCMD}\ and instead rely upon "make -s". This is less intrusive on all the Makefiles than the former. Idea from David Laight. * Rename the variables use to print messages.
