Any DJGPP-compiled executable will automatically look at the 'djgpp.env'
file for a section that starts with the name of the executable
(argv[0]), and load any variable settings from that section into its
environment.  Thus, if you add an [emacs] section to 'djgpp.env', you
can define the INFOPATH variable there and not have to worry about doing
it in DOS.  The 'djgpp.env' from DJGPP v2.01 comes with a preset [emacs]
section.

It is possible to disable this environment loading in your DJGPP
programs by including <crt0.h> and defining a null version of the
__crt0_load_environment_file() function.  This can reduce the size of
your compiled code by a few kilobytes, but will prevent it from having
access to the enhanced DJGPP environment.

Of course, for non-DJGPP programs, you'll need to set the INFOPATH
explicitly.
