This prevents an error when building skel.c caused by the $(m4) make variable not being defined. Particularly nasty since skel.c would still be created, thus causing make to think skel.c was up to date.

# Notes on building:
|
|
|
|
# Possible values for DEFS:
|
|
#
|
|
# By default, flex generates 8-bit scanners when using table compression,
|
|
# and 7-bit scanners when using uncompressed tables (-f or -F options).
|
|
# For flex to always generate 8-bit scanners, add "-DDEFAULT_CSIZE=256"
|
|
# to DEFS.
|
|
#
|
|
# For Vax/VMS, add "-DVMS" to DEFS.
|
|
#
|
|
# For MS-DOS, add "-DMS_DOS" to DEFS. See the directory MISC/MSDOS for
|
|
# additional info.
