Details:

When running following Makefile with GNU make 3.80 on Cygwin/Solaris/Linux it
outputs value of the Make variable instead of environment variable in case an
environment variable of the same name than Make variable exists.
[~]$ cat Makefile
IN_ENV = from_make
NOT_IN_ENV = from_make

all:
        echo $${IN_ENV}
        echo $${NOT_IN_ENV}

[~]$ make
echo ${IN_ENV}

echo ${NOT_IN_ENV}

=> that's OK
[~]$ export IN_ENV=from_env
[~]$ make
echo ${IN_ENV}
from_make
echo ${NOT_IN_ENV}

=> As variables are not exported I expect getting:
echo ${IN_ENV}
from_env
echo ${NOT_IN_ENV}
