OK - fair enough.
But, if I read the man page correctly LD_LIBRARY_PATH _prepends_ your
path before the standard paths. That would do fine for me. WINEDLLPATH
is appended after /usr/lib/wine.

I'm not getting why Windows DLL searching is relevant here. This is a

This was a slightly uninformed comment on my part, so I could be totally
off base here. And the code supporting dll directory lookups is
complicated. But ... I saw special cases for dealing with the build
directory, including this comment "/* if no build dir skip all the build
dir magic cases */" libs/wine/loader.c/first_dll_path. Those suggest to
me that someone was trying to stick a path in before /usr/lib/wine.
All that said, this isn't at all central to what I would like to do. All
I want is that WINEDLLPATH comes before /usr/lib/wine.
PS: Hin-Tak Leung, who got bit by this before me, found that WINEDLLPATH
broke/changed in November of 2006.
