# and switches are specific to it.
# The following macros are defined, names are for historical compatibility:
# OPTDEFINES - /Dxxx C macro flags based on user-specified OPTS
# COMPILERFLAGS - /Dxxx C macro flags independent of any configuration opttions
# COMPILERFLAGS - /Dxxx C macro flags independent of any configuration options
# crt - Compiler switch that selects the appropriate C runtime
# cdebug - Compiler switches related to debug AND optimizations
# cwarn - Compiler switches that set warning levels
# cflags - complete compiler switches (subsumes cdebug and cwarn)
# ldebug - Linker switches controlling debug information and optimization
# lflags - complete linker switches (subsumes ldebug) except subsystem type
# dlllflags - complete linker switches to build DLLs (subsumes lflags)
