This used to be the format of the error report: input.y:6.5-10: result type clash on merge function 'merge': [...] input.y:2.4-9: previous declaration In order to distinguish the actual error from the context provided, we rather this new output: input.y:6.5-10: result type clash on merge function 'merge': [...] input.y:2.4-9: previous declaration Another patch will introduce an "error: " prefix to all non-indented lines, giving yet better readability to the reports. * src/complain.h (SUB_INDENT): Move to here. * src/reader.c (record_merge_function_type): Use complain_at_indent to output with increased indentation level. * src/scan-code.l (SUB_INDENT): Remove from here. * tests/glr-regression.at: Apply this change.
