Strange behavior of 'exists' function. Need help with Makefile.

[Yevgen Krapiva]

Thanks Ulrich,

I've discovered the following issue:

!!!    This example works:  !!!

MY_FILE=	/usr/local/share/openjsip/conf/proxy.properties

do-check: 
.for f in ${MY_FILE}
.	if !exists(${f})
		@${ECHO_MSG} ">> File ${f} doesn't exists"
.	else
		@${ECHO_MSG} ">> File ${f} exists"
.	endif
.endfor

!!!  And this one doesn't: !!!

MY_FILE=	proxy.properties

do-check: 
.for f in ${MY_FILE}
.	if !exists(${DATADIR}/conf/${f})
		@${ECHO_MSG} ">> File ${DATADIR}/conf/${f} doesn't exists"
.	else
		@${ECHO_MSG} ">> File ${DATADIR}/conf/${f} exists"
.	endif
.endfor


So, I will use the first method... But anyway I would like to know why
the second
example doesn't work.

P.S. The second example was copied from tomcat6 port :\
