+ * scanner.c (load_line): Add pbuflen argument, don't make
+ buflen static. If maxlen == 0 or preprocessor_flag,
+ don't truncate at buflen, but at maxlen. In xrealloc add
+ 1 byte at the end for the terminating '\0'. Don't fill
+ with spaces up to buflen, but gfc_option.fixed_line_length.
+ (load_file): Adjust load_line caller. Add line_len variable.
+
* scanner.c (preprocessor_line): Only set current_file->line when errors
have not been encountered. Warn and don't crash if a file leave
preprocessor line has no corresponding entering line. Formatting.
load_line returns wether the line was truncated. */
