Build fail: unresolved external symbol mainCRTStartup

[Kevin Rushforth]

Hi Leonid,

Building JavaFX on Windows requires Cygwin, so it doesn't surprise me 
that it fails with a DOS shell.

The error you are seeing on cygwin seems like a mismatch where part of 
the build is trying to use a 32-bit build and part trying to use 64-bit.

My recommendation is to try the following, from a cygwin shell:

1. Ensure that your JAVA_HOME and PATH point to the same version of Java 
(the 32-bit Java).

2. Completely clean your repo

cd rt
gradle clean
rm -rf buildSrc/build buildSrc/.gradle .gradle


3. Rebuild, making sure you compile both media and webkit (not sure if 
needed, but better to remove one more variable):

gradle -PCOMPILE_WEBKIT=true -PCOMPILE_MEDIA=true sdk


See if the above will work.
