In this Makefile (between the "---" lines (and attached)), the "foo"
example doesn't work although the "bar" example works (if the files
foo.cc and bar.cc exists in the right places).


-------------------------------------------
/cygdrive/c/tmp/foo: /cygdrive/c/tmp/foo.cc
        g++ -Wall -W -o /cygdrive/c/tmp/foo /cygdrive/c/tmp/foo.cc

C:\tmp\bar: C:\tmp\bar.cc
        g++ -Wall -W -o C:\tmp\bar C:\tmp\bar.cc
-------------------------------------------


Version of make: GNU Make 3.81


I can't seem to find any information about this behaviour. It causes
some trouble when trying to set absolute paths (in .bash_profile) that
are later used in the Makefile. Setting the environment variable
OBJROOT to "${HOME}/obj" and then referring to it in the Makefile will
use a path like the "foo" one above; using "${HOME}/obj" directly in
the Makefile will work because "${HOME}" expands differently in
different circumstances. My "HOME" is set to
"C:\Users\my_name\cyghome".

Best regards
Henrik Stentjärn
