MinGW32 error: redefinition of 'struct timeval'

Hi,

After successfully compiling slrn under MinGW32 for some time I have
upgraded my MinGW installation and now compilation under the svn slrn
fails with the following message:

My apologies if this is a MinGW32 error, if so I shall backtrack to my
older, successful version.
