Uninstaller crashed on Windows 2000

[Pavel Roskin <proski@gnu.org>]

Hello!

HeapReAlloc() would crash on Windows 2000 is the original pointer is NULL.
This causes the Andreas Mohr's uninstaller to crash.

ChangeLog:
	programs/uninstaller/main.c
	Call HeapAlloc() on entries before HeapReAlloc() to avoid crash
	on Windows 2000.
