#
# CGO           C compiler's G Option.  This macro is appended to the -G
#               flag.
#
# ENV_CFLAGS    The additional CFLAGS.
#
# LANG          Added by haituanv.  LANG is defaulted to 'US' which builds the
#               US version of nmake.  The other choice is 'JAPAN' which is used
#               in the Ikura project.
#
# MESSAGE_FILE  Specifies the name of the text file which stores NMAKE's
#               error messages.  This macro depends on LANG

    @type <<
Define TARGET and VER environment variables to tell NMAKE what version to build.
The possible values of TARGET are 'dos' and the possible values for VER
are 'retail', 'debug' and 'cvinfo'. The object files are always built with /Zi
option. This is done to make it just a matter of linking when debugging. The
'retail' and 'cvinfo' versions differ in only that codeview information has
been added. For the 'retail' version the asserts are removed.
To see information about what is being built define INFO.
You can define LOGO when running under OS/2 to see the compiler logo and
define ECHO to see the command actually passed to the compiler. The switches
passed to the compiler can be changed from the command line by defining the
corresponding switches used in def.mak.
