Re: not a bug but some strange behaviour

[jean-luc malet]

$cat make.bat
set PATH=cygwin_Path;oldPath
make %*

$ cat /tmp/Makefile

export TEST_FLAG=test
SHELL=/bin/bash

test :
<tab> printf "$${TEST_FLAG}\n"

test2 :
<tab> printf "${TEST_FLAG}\n"

test3 :
<tab> printf "$${ENV_VAR1}\n"

test4 :
<tab> printf "${ENV_VAR1}\n"

test5 :
<tab> ENV_VAR1=${ENV_VAR1}; /bin/bash somescriptthatdoprintfenv_var1



$ export ENV_VAR1=fromtheenv
----- cygwin env (make is called throught a .bat file) -----
$ make.bat test
<empty line>
$ make.bat test2
test
$make.bat test3
<empty line>
$make.bat test4
fromtheenv
$make.bat test5
fromtheenv

------ from an interactive shell, cygwin env ----
$make test
test
$make test2
test
$make test3
fromtheenv
$make test4
fromtheenv
$make test5
fromtheenv

------- linux ------
always working

to make it short : if you call the subshell by setting the env
variable on the same line it will ever work
if you try to access some env variable in the makefile it always work
if you try to use the env variable into one of the command it fails
depending on the context.....
