Problem building gmime on Windows (again)

Hi,

As usual, new version of gmime equals new compilation problems. :-)
This time the error is as follows:

 gcc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I../util -DGMIME_VERSION=\"2.2.9\" 
-DGMIME_MAJOR_VERSION=2 -DGMIME_MINOR_VERSION=2 -DGMIME_MICRO_VERSION=9

Any ideas?
