Incomplete location in automake-1.6.3 error message with conditionals

[Harlan Stenn]

In automake-1.6.3 I have a Makefile.am Somewhere in a project that
erroneously attempts to augment CFLAGS using:

 if COND_FOO
   CFLAGS = @CFLAGS@ -g -rdynamic
 endif

which (reasonably) generates the following when I run automake:

 configure.in:NN: CFLAGS was already defined in condition TRUE, which
 implies condition COND_FOO

 CFLAGS (user, where = configure.in:NN) =
 {
   COND_FOO => @CFLAGS@ -g -rdynamic
   TRUE => @CFLAGS@
 }

but it doesn't tell me the Makefile.am that contains the offending lines.
