[vlc-devel] [PATCH] Make cached module configuration on 64 bits work again

This patch resolves the problems I encountered after applying the patch 
for src/modules/cache.c with the 64 bit version of vlc.

The structure is 64 bit large but the cached module configuration was 
fed with the lower 32 bits only. The bit fields containing b->removed 
etc. where not cached this way. That was also the reason for the qt 
expert configuration dialog when it came across "removed" configuration 
items (which where not recognized as removed by parsing plugins.dat).

Making the i_flags 64 bits large on 64 bit compilation resolves that.
