I was never convinced it was a real problem,
and we haven't had any changes to msvcrt/environ.c
in ages. So it's probably more likely invalid.

I read his report more carefully, and see that he was
saying that putenv cleared *other* env vars, so I wrote
the test case

#include <stdio.h>
#include <stdlib.h>
void show()
{
        const char *foobie=getenv("foobie");
        if (foobie)
                printf("foobie ok, %s\n", foobie);
        else
                printf("foobie not found\n");
        foobie=getenv("bar");
        if (foobie)
                printf("bar ok, %s\n", foobie);
        else
                printf("bar not found\n");
}
int main(int argc, char **argv)
{
       show();
       putenv("bar=bletch");
       show();
}

and ran it with
i586-mingw32msvc-gcc env.c
foobie=xyz wine a.exe

Worked fine.

Also, there's a known issue even in Windows with
having too many environment variables; space
is limited.    The user said that commenting out
some variables fixed his problem.  So that's
what he was probably running into, and that's
probably what fixed his problem.

If there is a real problem, it might be that
Wine preserves too many Unix environment variables,
thus using up the precious space in wine.

In any case, we didn't fix anything, so this should
either be left open or closed as invalid.
Let's close it as invalid for now, but 
if anyone runs into the "runs out of env space
sooner in wine than windows" problem, let's
reopen it as a new bug.
