RE: not a bug but some strange behaviour

Interestingly, I failed to reproduce your problem:

$ ./make.bat test3

C:\Documents and Settings\martind\playpen\jlm-2009-11-30>C:\cygwin-1.5\bin\make test3

printf "${ENV_VAR1}\n"

fromtheenv

I tried with Cygwin 1.5 and 1.7. Here's more information about the 1.5 versions:

$ uname -a

CYGWIN_NT-5.1 vm-martind 1.5.25(0.156/4/2) 2008-06-12 19:34 i686 Cygwin

$ bash --version

GNU bash, version 3.2.49(22)-release (i686-pc-cygwin)

$ make --version

GNU Make 3.81

There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A

PARTICULAR PURPOSE.

This program built for i686-pc-cygwin

The exact test case I used wasn't quite the same as you gave:

$ cat make.bat

C:\cygwin-1.5\bin\make %*

$ cat Makefile

export TEST_FLAG=test

SHELL=/bin/bash

test :

printf "$${TEST_FLAG}\n"

test2 :

printf "${TEST_FLAG}\n"

test3 :

printf "$${ENV_VAR1}\n"

test4 :

printf "${ENV_VAR1}\n"

test5 :

ENV_VAR1=${ENV_VAR1}; /bin/bash somescriptthatdoprintfenv_var1

If I had make.bat run "make", then it ended up invoking itself. My bat-fu is weak:

$ cat make.bat

set PATH=C:\cygwin-1.5\bin;%PATH%

make %*

$ export ENV_VAR1=fromtheenv

----- cygwin env (make is called throught a .bat file) -----

$ make.bat test

$ make.bat test2

test

$make.bat test3

$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.....
