Bingo, thanks. It should indeed be seeing the correct string.

Sorry for the many lines here (I ended upjust using +all), but I
*think* it is revealing. The following is from a grep for 'LM_' and
all the returned lines seem to be connected to my env variable (the
initial numbers on the lines are line numbers in the log file, added
for me by grep).

If you look at the CompareStringW() calls, there seems to be something
screwy going on. 

Looking at line 727372, the first argument is "MODEL_TECH\n" whose
length is 11 characters, and it is being compared to
"LM_LICENSEMODEL_TECH\n" which looks suspiciously like it is
"LM_LICENSE_FILE" truncated at the 11th character and then having
"MODEL_TECH" appended.  The same algorithm works for lines 736061,
737557, 739075, 740615 and 742177 modulo some non-printing
characters. Line 1469993 seems to break this though.

As I don't know what it is (a) intending and (b) supposed to be doing,
I cannot tell if this is just weird shit or possibly a Wine bug

> (b) maybe a +winsock trace will give you that

I think it is not even getting as far as knowing where to open a
socket so it doesn't try, but I shall keep that in mind for later on.
