For the sake of completeness and self-containedness, let me type in
what the fix was that was linked in those blogs.

To resolve the

mysql.c: In function 'Init_mysql':
mysql.c:2015: error: 'ulong' undeclared (first use in this function)

error, the workaround to this bug is to add the line

#define ulong unsigned long

to mysql.c near the top with the other preprocessor defs.  I can
confirm that this fix enabled me to successfully compile the
software.  But see Mat's post later in this thread for what is
probably a better fix.
