[eclipse-pmc] PMC Bug Fix Request: to fix broken multi-select FileDialog

[Grant Gayed <Grant_Gayed@xxxxxxxxxx>]

GOALS/BENEFITS:

In SWT's 64-bit Windows port the FileDialog
fails to open if it has style SWT.MULTI (on 64-bit Windows XP and 64-bit
Windows 2003 Server only).  A callback in SWT is not being found because
its signature is missing one piece of markup that converts a variable from
type int to long (32 to 64 bits) during the 64-bit build process.

The initial reported case in Eclipse
where this fails is when adding an external JAR to a Java project's build
path.  However there are other scenarios in Eclipse where multi-select
FileDialogs are used as well, and they will fail to open in a similar manner.

ASSOCIATED BUG:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=237432
(Add External JARs in Java Build Path fails consistently)

RISKS:
Very Low.  SWT's Windows port only
runs on the Windows version of Eclipse, and in SWT's 32-bit port this is
not a code change because it just appears as an added comment.

PERFORMANCE IMPACT:
None
