xrdp-droppriv.c is erroneously including os_calls.c rather than os_calls.h This leads to a link failure on Ubuntu 20.04:- /usr/bin/ld: xrdp-droppriv.o: undefined reference to symbol 'dlclose@@GLIBC_2.2.5' The error does not happen with later glibc versions, as libdl is included in libc for these versions.
