more than one copy of `eiffel_curl.h' could be present, meaning that multiple values of each static declared variables could be present at run-time and in one case, one was properly initialized, but not the other. Fixes bug#13671. git-svn-id: https://svn.origo.ethz.ch/eiffelstudio/trunk/Src/library/cURL@71399 8089f293-4706-0410-a29e-feb5c42a2edf
