In distorm.c the lines around 320 look like:

                unsigned int opcode = di->opcode;
                unsigned int prefix = FLAG_GET_PREFIX(di->flags);
                mnemonic = (const _WMnemonic*)&_MNEMONICS[opcode]; <--
                unsigned int size = di->size;
                _OffsetType offset = di->addr & addrMask;

Visual C doesn't permit assignments before declarations in some instances. The solution is to move the flagged line to be after all declarations are completed, e.g.,

                unsigned int opcode = di->opcode;
                unsigned int prefix = FLAG_GET_PREFIX(di->flags);
                unsigned int size = di->size;
                mnemonic = (const _WMnemonic*)&_MNEMONICS[opcode]; <--
                _OffsetType offset = di->addr & addrMask;

A similar issue exists in prefix.c, line 141:

        for (unsigned int index = 0;
                (ci->codeLen > 0) && (index < INST_MAXIMUM_SIZE);
                ci->code++, ci->codeLen--, index++) {

Needs to be replaced with:

        unsigned int index;
        for (index = 0;
                (ci->codeLen > 0) && (index < INST_MAXIMUM_SIZE);
                ci->code++, ci->codeLen--, index++) {
