Thanks for the detailed explanation.
I now realize that there are many different values that are
similarly affected.
Cheers,

Symbol redirects in import libraries are defined by "==", while
"=" in def files is used to rename a symbol on export, while

These symbols on 64 bit should resolve to _findfirst64i32/_findnext64i32
functions, like in other CRT libraries and header files.
The UCRT 32 bit aliases are kept as they were before (even if
they are known to be incorrect); they are corrected in a separate
later commit.

This alias is already provided by the msvcrt-common.def.in file.

CRT header files ensures that time symbols without 32/64 suffixes are not
emitted. And linker always sees time symbols with explicit 32 or 64 suffix
name.
When CRT header files are not included then 32-bit MSVC compiler + linker
treats symbols without "64" suffix name as functio

Hi,
thanks for working on this and unifying this inlining issues. Looks good to me.

There is no symbol change or removal.
File msvcrt-common.def.in adds just symbol aliases, so include it in CRT
def files after having all symbols declared.
Note that some def files use DECORATED_EXPORT macro from func.def.in file,
so include func.def.in at beginning of each def file.

msvcrt versions 8.0 - 12.0 and UCRT do not have _strcmpi symbol.
For these CRT versions (which have NO_STRCMPI_ALIAS) is later in the file
symbol _strcmpi defined as an alias to _stricmp symbol.
So for these affected CRT versions define strcmpi as an alias to _stricmp.

Add a new helper macro ADD_UNDERSCORE_DATA for defining alias for

Move symbol aliases into categories and document from which oldnames.lib
version they comes from or what is the reason for defining them (C99, POSIX
or GNU compatibility).
Document all symbols from the late
So it can be used in any def file, not only msvcrt-based.

Deduplicate aliases from msvcrt.def.in and ucrtbase.def.in to

Note that powl alias was defined only in ucrtbase.def.in, so do not define

msvcrt versions 8.0 - 12.0 and UCRT do not have _utime symbol.
For these CRT versions (which do not have FIXED_SIZE_SYMBOLS) is later in
the file symbol _utime defined as an alias to _utime32 or _utime64 symbol.
So for these affected CRT versions define utime as an alias to _utime32 or
_utime64.
Other symbol aliases for ISO C functions are already in msvcrt-common.def.in.

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.
