I can't imagine MariaDB being much different from MySQL which I 
successfully compiled MySQL on Cygwin over a year ago. It was more a 
proof of concept than a practical project but I thought I'd share the 
notes I made at the time:

User / Group Creation:
-----------------------
Cygwin takes its users and groups from its Windows host.
I found that I couldn't create a new group if a user with the same name 
already exists. This prevented me from creating both a user and group 
called ‘mysql’ so I used the group name, ‘mysqlgroup’.

# create a Windows mysqlgroup group
net localgroup mysqlgroup /add
# create a mysql user
net user mysql /add
# add 'mysql' user to 'mysqlgroup'
net localgroup mysqlgroup mysql /add

# Update Cygwin's user & group files
mkpasswd -l -u mysql >> /etc/passwd
mkgroup -l -g mysqlgroup >> /etc/group


Compilation:
------------
Follow instructions at 
http://dev.mysql.com/doc/refman/5.0/en/installing-source-distribution.html

The default C compiler flag -O3 doesn't work properly under Cygwin with 
gcc 3.4.4

Ensure readline is installed and use:
./configure --without-readline CFLAGS=-O2

chown -vR mysql:mysqlgroup /usr/local/*/*
bin/mysql_install_db --user=mysql   # works fine in Cygwin

This creates the data directory and initialises the mysql and test 
databases.


Hope this helps,
Anthony
