./devtool.log:/usr/bin/ld: multiple definitions of symbol  
_strict_erasures
./devtool.log:../lib/.libs/librpm.a(fsm.o) definition of  
_strict_erasures in section (__DATA,__data)
./devtool.log:../rpmio/.libs/librpmio.a(iosm.o) definition of  
_strict_erasures in section (__DATA,__data)

Seems to be some kind of local that got exported ?

Worked around with "static int strict_erasures = 0;"
