-              makefiles for wgrib2 upto v3.0.0
-                   gnu make v3 vs v4
-
-
-Gnu make is needed for wgrib2's makefile.  Gnu make v4 (ex. v4.2
-and v4.3) is incompatible with the gnu make v3 by the way they
-treat the # character.
-
-   foo := $(shell echo '\#abc')
-     old gnu make: will print #abc
-     new gnu make: will print \#abc 
-
-   fix introduced with v3.0.1 (staight from the gnu make release notes)
-
-   H:=\#
-   foo := $(shell echo '$Habc')
-     old gnu make: will print #abc
-     new gnu make: will print #abc
-
-If want to compile an old version of wgrib2 on a system that
-has gnu make v4, you can do one of the following,
-
-   a)  build wgrib2 with gnu make v3.x
-   b)  edit grib2/makefile, replace /# by #.
-   c)  follow the fix using H:=\# (see above)
-        makes the makefile compatible with gnu make v3 and v4.
