winedbg --gdb shows multiple segfaults during any app startup

[Ilya Basin]

In both 1.3.8 and git winedbg --gdb or plain gdb catches several
segfaults, but if I ignore them, the program works.

$ CC="ccache gcc" ./configure CFLAGS="-g -O0"
make
./wine winedbg.exe --gdb notepad

Wine-gdb> cont
Continuing.

Program received signal SIGSEGV, Segmentation fault.
0x7e942cf4 in create_alpha_bitmap (color=0x33c, mask=0x338, src_info=0x1319a8, color_bits=0x7ebf411c) at cursoricon.c:664
664             ptr[0] = ptr[0] * alpha / 255;
Wine-gdb> 
Continuing.
...
Program exited normally.
Wine-gdb> quit

These faults are normal, they are part of how wine more-or-less transparently 
switches access to GDI bitmaps data.
