+size_t can be defined as an unsigned int instead of long unsigned int so
+replace 1UL to (size_t)1 when calling max function

+Subject: [PATCH] SerialPort.cpp: don't use high baudrates when not available
+
+On certain architectures (namely Sparc), the maximum baud rate exposed
+by the kernel headers is B2000000. Therefore, the current libserial
+code doesn't build for the Sparc and Sparc64 architectures due to
+this.
+
+In order to address this problem, this patch tests the value of
+__MAX_BAUD. If it's higher than B2000000 then we assume we're on an
+architecture that supports all baud rates up to B4000000. Otherwise,
+we simply don't support the baud rates above B2000000.
+
+Fixes build failures such as:
+
+SerialPort.cpp: In member function 'int LibSerial::SerialPort::Implementation::GetBitRate(const LibSerial::BaudRate&) const':
+SerialPort.cpp:1226:14: error: 'BAUD_2000000' is not a member of 'LibSerial::BaudRate'
+         case BaudRate::BAUD_2000000:
