test -x path returns 0 (true) for executables and directories. I tested
with DJGPP port of bash 2.04's built-in test and the DJGPP port of
shellutils 1.12:

bash-2.04$ if [ -x c:/djgpp ]; then echo Yo; fi
Yo
bash-2.04$ $DJDIR/bin/test -f c:/djgpp/bin/ls.exe ; echo $?
0
bash-2.04$ $DJDIR/bin/test -x c:/djgpp/bin/ls.exe ; echo $?
0
bash-2.04$ $DJDIR/bin/test -x c:/djgpp/license ; echo $?
1
bash-2.04$ $DJDIR/bin/test -x c:/djgpp/bin/ls ; echo $?
0
bash-2.04$ if [ -x $DJDIR/bin/ls.exe ]; then echo Yay; fi
Yay
bash-2.04$ if [ -x $DJDIR/bin/ls ]; then echo Yay; fi
Yay
bash-2.04$ if [ -x $DJDIR/bin ]; then echo Yay; fi
Yay

Bye,
