# --------------------
# 01p,27nov12,xhs  Fix default vsb/vip error,WIND00387505
# 01o,07may09,dlk  Handle USE_IPDEFINES in VIP or BSP build (WIND00165503).
# 01n,02sep08,mze  stop creating the IPCOM_LIBCONFIG file
# 01m,01may08,dlk  Support USE_IPDEFINES to obtain defines from ipcom.
# 01l,04mar08,pee  temporary workaround to accomodate emake
# 01k,31oct07,pee  WIND00109695
# 01j,19oct07,pee  WIND00105890
# 01i,28sep07,pee  WIND00105890
# 01h,17sep07,tkf  Fix CQ:WIND00104875.
# 01g,19jun07,tpw  Use WRVX_COMPBASE vs. WIND_COMPONENTS correctly.
# 01f,13jun07,tkf  Convert backslash characters into forwardslash in
#                  WIND_COMPONENTS.
# 01e,24may07,tkf  Move _IPCOM_OBJ_DIR to defs.ipcom. Generate ipcom_ipdomain
#                  in _IPCOM_OBJ_DIR instead of in the ipcom make dir. Also
#                  added user object dependency on ipcom_ipdomain.
# 01d,10may07,tkf  If there are CPU variants, generate ipcom_libconfig only
#                  for the CPU class.
# 01c,25apr07,tkf  Add dependency rule for statTbl.c. Also added rules for
#                  generating library build configuration cache file.
# 01b,03mar07,tkf  Added rule to create IPNET include path file.
# 01a,09nov06,tkf  created.

# DESCRIPTION
# This file is included in rules.bsp and rules.library for both the kernel and
# user builds to define make rules that pertain to IPCOM requirements.
