A compile in the TUI somehow had "lines" defined as a macro. This caused a compile error when including source-cache.h after whatever header did that. I tracked this down to a #define in /usr/include/term.h, so I just changed source-cache.h to avoid the clash. gdb/ChangeLog 2019-01-22 Tom Tromey <tom@tromey.com> * source-cache.h (class source_cache) <get_source_lines, get_plain_source_lines, extract_lines>: Rename "lines" parameter.
