1. Follow the instructions at 
http://sapdb.2scale.net/moin.cgi/PortBuildTools. I suggest that you set 
$OS to WIN32 and $OSSPEC to CYGWIN

2. Search sys/src/tt/toolvas-tpl.pl.tt for WIN32 and decide whether the 
     predicate should really be for $OS or for $OSSPEC.

3. I'll ask our tools guru whether he allows the usage of a CC variable 
(or CCFAMILY variable for CC, CXX, linker etc).  Setting compiler flags 
should really depend on that variable just in case someone wants to port 
SAP DB to SUN + gcc.

4. grep sys/src/tt for other appearances of WIN32 to check if they apply 
to CYGWIN or not

5. ditto for sys/desc

Once the build tools are working, do the same for the real sources.

I have cygwin installed on my home machine, so I can probably help you 
out once you are stuck.

Most evenings (German time), I can be reached via IRC 
(irc://irc.freenode.net, #sapdb).
