bug on RTOS SDK 1.5.0

[sportybj]

Please check RTOS SDK 1.5.0, which is in poor QA. Please find in file include/lwip/lwip/multi-threads/sockets_mt.h, there is something like:
#define bind(a,b,c) lwip_bind_mt(a,b,c);
which will cause error when compling statements like while ( bind(xxx)<0 )

People can hardly believe that the version through such a QA is reliable. So please take a check on that
