API for __getmainargs() function in msvcrt10.dll is same as __GetMainArgs()
function in crtdll.dll. It is slightly different than in any other msvcrt
versions. It returns void and does not the pointer to the _startupinfo
structure as a last argument.
So for compatibility with mingw-w64 startup
For 32-bit time_t (detected by _USE_32BIT_TIME_T), functions _fstat32(),
_fstat() and fstat() are same. So fstat() can be defined as simple alias
in def file.
Same applies for functions _fstat64i32(), _fstat() and fstat() when time_t
is 64-bit.
Simplify fstat() function, remove it from
All CRT import libraries provides UCRT-compatible *stat* symbols since
commit b4638756158e947ce3ddde9e1b3b6f1f63d2ba03.
So define all stat* macros consistently with definitions of aliases in def
files based on UCRT. There is no need to have ifdef for non-UCRT version
anymore.

GCC documentation for alias attribute for variables says:
https://gcc.gnu.org/onlinedocs/gcc/Common-Variable-Attributes.html
Using both the alias and the alias target to access the same object is
undefined in a translation unit without a declaration of the alias with
the attribute.
So
msvcr40d.dll is debug version of the msvcrt40.dll and provides additional
debugging functions.
msvcr40d.def.in def file was generated by gendef from the original
msvcr40d.dll library version and modified with same changes (mostly
documentation) which were done to the msvcrt40.def.in def file.

WinMain() entry point defined by the application is called by mingw-w64
startup code, more precisely by function main() from crtexewin.c file.
mingw-w64 startup code in file crtexewin.c calls _ismbblead() function.
Function _ismbblead() is not available in earlier versions of crtdll.dll
and is
API for __getmainargs() and __wgetmainargs() functions in msvcrt20.dll is
slightly different than in new msvcrt versions. In msvcrt20.dll these
functions return void and take new_mode parameter instead of the pointer to
the _startupinfo structure.
So for compatibility with mingw-w64 startup code,

Hello, have you looked at this and other changes?

Change library name to uppercase CRTDLL.dll and remove DATA keyword for all
time function symbols. This is how the original crtdll.dll library is defined.

Symbol _fstat64i32 is available in all 64-bit CRT import libraries as an
alias. For 32-bit CRT import libraries it is present as native import
symbol since msvcr80.
MinGW-w64 fallback implementation of _fstat64i32() function uses _fstat64()
call which in 32-bit versions is available since msvcr70
Some find, stat and time aliases are missing in UCRT def files:
api-ms-win-crt-filesystem-l1-1-0.def.in api-ms-win-crt-time-l1-1-0.def.in
They are already present in ucrtbase.def.in file after change from the
commit b4638756158e947ce3ddde9e1b3b6f1f63d2ba03.
Add those aliases which are missing.
Symbols __p___argv, __p__acmdln, __p__commode, __p__fmode, and __p__wcmdln
are available in X64 version of msvcr80.dll. This was clarified and fixed
in commit e0426704cce399a7517e4ec71360bbd1d5f880e3. So remove duplicated
definitions of fallback functions.

Both symbols refers to global variable, not the function. So mark them with
DATA for all platforms. gendef detects that _mbcasemap is DATA for all I386
versions of msvcrt.dll (Visual C++ 5.0, 6.0, Win9x, 2000, XP, ... up to 10).
But gendef since Windows XP version of msvcrt.dll cannot autodetect

This file contains definitions of symbol aliases for any CRT library. It is
already used by msvcrt, crtdll and ucrt. So rename msvcrt-common.def.in to
crt-aliases.def.in as new name better match the purpose of the file.
