Hi,

I seem to experience some particular weirdness wrt make(1)'s idea of
when a file exists or not:

In a Makefile:

FILE1=3D  ${PREFIX}/lib/libGL.so.5
FILE2=3D  /usr/pkg/lib/libGL.so.5
=2Eif exists(${FILE1})
BAR=3D    blah    =20
=2Eendif
=2Eif exists(${FILE2})
BLAH=3D   blah
=2Eendif


Now, we would assume that, given that /usr/pkg/lib/libGL.so.5 exists,
and that PREFIX is indeed /usr/pkg (ie FILE1 =3D=3D FILE2 and exists) both
BAR and BLAH should be set, right?

Behold:

red-stripe# make show-var VARNAME=3DBAR

red-stripe# make show-var VARNAME=3DBLAH
blah
red-stripe#=20


Now let's change /usr/pkg/lib/libGL.so.5 to /usr/pkg/lib/libGL.so (and
FILE1 accordingly), and we get:

red-stripe# !119
make show-var VARNAME=3DBAR
blah
red-stripe# !120
make show-var VARNAME=3DBLAH
blah
red-stripe#=20


Ok, now change libGL.so to libGL.so.5.501:

red-stripe# !119
make show-var VARNAME=3DBAR

red-stripe# !120
make show-var VARNAME=3DBLAH
blah
red-stripe#=20

Now change /usr/pkg/lib/libGL.so to /usr/pkg/include/GL/gl.h:

red-stripe# !119
make show-var VARNAME=3DBAR
blah
red-stripe# !120
make show-var VARNAME=3DBLAH
blah
red-stripe#=20


This does not make any sense to me.  Note that libGL.so and libGL.so.5
are symlinks, libGL.so.5.501 the actual file.=20

What's up with this - anybody have any idea?
