environment variables only in uppercase

[Randy Maddox]

Hello,

I am experiencing what appears to be a possible bug in the make utility.  I
am running DJGPP for WinDoze 2K and make will only obtain the value of an
environment variable if the name used in the make file is all caps, i.e.,
$(ENVVARIABLE), regardless of the case of the name as actually set for the
environment variable.

I am using the following version of make:

>make --version
GNU Make version 3.79.1, by Richard Stallman and Roland McGrath.
Built for i386-pc-msdosdjgpp

The following make file demonstrates the problem if run after setting
EnvVariable to some_value so that a display of environment variables using
the set command shows:  EnvVariable=some_value

# sample make file

all:
        @echo EnvVariable = $(EnvVariable)
        @echo ENVVARIABLE = $(ENVVARIABLE)

#end of this file

The output from running make against this make file generates the following
output on my machine:

>make all
EnvVariable =
ENVVARIABLE = some_value

I have never encountered this issue with any previous version of make on
this or any other platform, and so was quite surprised.  Is this a bug?

Thanks.
