Where do i set the buffer space?

When enabling debug i get a long list of compile errors.

src/lwip-1.3.0//src/core/tcp_out.c: In function 'tcp_write':
src/lwip-1.3.0//src/core/tcp_out.c:97: error: expected ')' before 'U16_F'
src/lwip-1.3.0//src/core/tcp_out.c: In function 'tcp_enqueue':
src/lwip-1.3.0//src/core/tcp_out.c:141: error: expected ')' before 'U16_F'

so no debug info at the moment.
