Cygwin 2.5.1 x86_64 g++ 5.3.0In Cygwin, build of lftp 4.7.2 fails in two places: (1) /home/andrex/dev/cygwin/lftp/lftp-4.7.2-1.x86_64/src/lftp-4.7.2/src/xmalloc.h:31:38: error: expected ';', ',' or ')' before '=' token char *xstrdup(const char *s,int spare=0); ^ g++ seems not to like the default value 'spare=0' in the function declaration.
I'm convinced g++ actually likes that just fine. The problem is that this header is being pulled in by a plain C source file: lftp_rl.c. But C does no have default arguments; those only exist in C++.
The underlying reason appearst to be that there is a conflict between src/History.h and /usr/include/readline/history.h.
This file wants to include readline's history.h, but "thanks" to Windows's harebrained handling of filename cases, gets src/History.h instead. Which is a C++ header file, and new with 4.7.2.
(2) /home/andrex/dev/cygwin/lftp/lftp-4.7.2-1.x86_64/src/lftp-4.7.2/src/xmalloc.h:32:21: error: expected ';', ',' or ')' before '&' token char *xstrset(char *&mem,const char *s);
Same problem, same cause: that is not legal C code, so the C compiler is correct in rejecting it.
