Subject: [PATCH] wmaker: Fix compiler warnings about pointer <--> integer
conversion
There may be issues with running applications in 64-bit mode when
they were written with tacit assumptions about 32-bit platforms.
For example,
* Assuming that a pointer can be cast back and forth to an integer
The reason is that the size of the integer and pointer may be different.
See the description of "[PATCH] Warn when casting a pointer (constant)
to an integer of different size." in the gcc mailing list
http://gcc.gnu.org/ml/gcc-patches/2005-12/msg01881.html
where it was also suggested the use of casts to uintptr_t. This is
what this patch does.
As a result the following warnings (from src/) are fixed:
defaults.c: In function 'wReadDefaults':
defaults.c:1446: warning: cast to pointer from integer of different size
defaults.c:1457: warning: cast to pointer from integer of different size
defaults.c:1471: warning: cast to pointer from integer of different size
defaults.c:1486: warning: cast to pointer from integer of different size
icon.c: In function 'appearanceObserver':
icon.c:67: warning: cast from pointer to integer of different size
menu.c: In function 'appearanceObserver':
menu.c:112: warning: cast from pointer to integer of different size
switchmenu.c: In function 'wsobserver':
switchmenu.c:452: warning: cast from pointer to integer of different size
window.c: In function 'appearanceObserver':
window.c:140: warning: cast from pointer to integer of different size
window.c: In function 'wWindowChangeWorkspace':
window.c:2217: warning: cast to pointer from integer of different size
workspace.c: In function 'wWorkspaceNew':
workspace.c:135: warning: cast to pointer from integer of different size
workspace.c: In function 'wWorkspaceDelete':
workspace.c:214: warning: cast to pointer from integer of different size
workspace.c: In function 'wWorkspaceForceChange':
workspace.c:634: warning: cast to pointer from integer of different size
workspace.c: In function 'wWorkspaceRename':
workspace.c:1330: warning: cast to pointer from integer of different size
workspace.c: In function 'wWorkspaceRestoreState':
workspace.c:1514: warning: cast to pointer from integer of different size
