Description:
sql_bitmap.h: In member function 'my_bool Bitmap<default_width>::is_overlapping(const Bitmap<default_width>&) const [with unsigned int default_width = 128u]':
table.cc:4025:   instantiated from here
sql_bitmap.h:68: error: cannot convert 'const MY_BITMAP' to 'const MY_BITMAP*' for argument '2' to 'my_bool bitmap_is_overlapping(const MY_BITMAP*, const MY_BITMAP*)'

After applying the fix, mysql is compiled successfully.

P.S. 5.1.17-beta, community edition. Downloaded a few hours ago from the http://dev.mysql.com/downloads/mysql/5.1.html

gcc (GCC) 4.1.1 (Gentoo 4.1.1-r3)

How to repeat:
1. Download "Compressed GNU TAR archive (tar.gz) 5.1.17-beta" from
http://dev.mysql.com/downloads/mysql/5.1.html
2. Configure and run make

configure script to get error

I have just tested different build configurations and the error occurs only when running configure with additional parameters:
 --enable-big-tables
 --with-max-indexes=128

Without them, mysql compiles OK.

Configuration file attached was tested against mysql-5.1.17-beta without any patches applied.

Command line used in the file is taken from custom gentoo ebuild, based on 5.1.15-beta.
