winedbg is not finding debug symbols, anybody know what I'm doing wrong?

Whenever I run winedbg (or when wine runs it in response to an exception),
it fails to find debug symbols.  Looking at disassembled code is making my
brain numb.  I "export STRIP=false" before configure to ensure that the
Makefile doesn't strip anything, and gdb finds everything just fine.  So what
am I doing wrong?  The doc says winedbg should know all about this,
and I see examples of people's winedbg runs on the internet where 
winedbg is automagically loading tons of symbols for them (I only
seem to get libntdll.dll.so working).  Here's a typical run:

Whatever I do, even if winedbg makes a show of loading my symbols, it never seems to synch up with
my source files, except maybe for libntdll.dll.so... anyone got ideas?  Thanks,
