417 /* We use FormatMessage() to get strings from catalog, get system error
418    messages, etc. FormatMessage() tends to return Windows* OS-style
419    end-of-lines, "\r\n". When string is printed, printf() also replaces all the
420    occurrences of "\n" with "\r\n" (again!), so sequences like "\r\r\r\n"
421    appear in output. It is not too good.
422 
423    Additional mess comes from message catalog: Our catalog source en_US.mc file
424    (generated by message-converter.pl) contains only "\n" characters, but
425    en_US_msg_1033.bin file (produced by mc.exe) may contain "\r\n" or just "\n".
426    This mess goes from en_US_msg_1033.bin file to message catalog,
427    libompui.dll. For example, message
428 
429    Error
430 
431    (there is "\n" at the end) is compiled by mc.exe to "Error\r\n", while
432 
433    OMP: Error %1!d!: %2!s!\n
434 
435    (there is "\n" at the end as well) is compiled to "OMP: Error %1!d!:
436    %2!s!\r\n\n".
437 
438    Thus, stripping all "\r" normalizes string and returns it to canonical form,
439    so printf() will produce correct end-of-line sequences.
440 
441    ___strip_crs() serves for this purpose: it removes all the occurrences of
442    "\r" in-place and returns new length of string.  */
