Hi Michael,

Please fix the gcc-ism you introduced to the 3.15 branch in commit
8edefb9d which is currently causing all Jenkins' Windows builds to fail:

dbUnitTest.c: In function ‘testdbGetArrFieldEqual’:
dbUnitTest.c:223:32: error: pointer of type ‘void *’ used in arithmetic
[-Werror=pointer-arith]
         for(n=0; n<N; n++, gbuf+=vSize, pbuf+=vSize) {
                                ^
dbUnitTest.c:223:45: error: pointer of type ‘void *’ used in arithmetic
[-Werror=pointer-arith]
         for(n=0; n<N; n++, gbuf+=vSize, pbuf+=vSize) {
                                             ^
cc1: some warnings being treated as errors

Another option now in my ~/configure/CONFIG_USER.Common.linux-x86_64 file:

ifdef BASE_3_15
  OP_SYS_CFLAGS += -Werror=pointer-arith
  OP_SYS_CFLAGS += -fvisibility=hidden
  OP_SYS_CXXFLAGS += -fvisibility-inlines-hidden
endif
