PATCH: squash three warnings in dlls/shell32/brsfolder.c

[Gerald Pfeifer]

A few weeks ago, on SUSE Linux 10.1 with GCC 4.1, I started getting
the following warnings:

  brsfolder.c:591: warning: value computed is not used
  brsfolder.c:599: warning: value computed is not used
  brsfolder.c:626: warning: value computed is not used

The patch below addresses this one way -- by explicitly telling the
compiler we are not interested in the return value.

Gerald

ChangeLog:
Avoid compiler warnings by explicitly stating when we are not
interested in the results of function calls.
