If the comment is too short it won=E2=80=99t w= ork. No, that=E2=80=99s wrong. To my eternal embarrassement but also great relief this substitution has the effect of commenting the *following* line which frees up previously claimed resources (a bunch of characters making up the file name). The other comments I tested must have ended on \n, so they did not have this effect. Thanks to Julien for pointing this out! So! Creating a memory leak lets us successfully build ant-bootstrap. It does not, however, get us all the way through the Java bootstrap.
