win32: retire visual studio 2013 support
Browse files Browse the repository at this point in the history 
I recently (tried) to test VS 2013 builds, but while vs2013 in theory
supports mixed declarations and code, in practice that support is
broken, and failed to build toke.obj:

The one case I looked at in detail, VS 2013 required an extra ; after
a conditional statement to accept the following declaration, for
example:

```
C:\Users\Tony\dev\perl\git>cl /c mixed.c
Microsoft (R) C/C++ Optimizing Compiler Version 18.00.21005.1 for x64
Copyright (C) Microsoft Corporation.  All rights reserved.

mixed.c
mixed.c(8) : error C2143: syntax error : missing ';' before 'const'
mixed.c(9) : error C2065: 'pend' : undeclared identifier
mixed.c(9) : error C2100: illegal indirection

C:\Users\Tony\dev\perl\git>type mixed.c
/* adapted from S_intuit_more() in toke.c.
   don't run this code
*/
int g(const char *p) {
  if (!p)
    return (0);

  const char * const pend = p+1;
  return *pend;
}
```

regcomp.obj also failed to build due to the use of the "inline"
keyword in regcomp.h.  This is fairly trivially fixable but
inline is also C99.

Despite these build issues we haven't received any error reports for
VS2013, so I don't think it's worth re-working any mixed declarations
to support it.

It might be worth updating regcomp.h to use PERL_STATIC_INLINE
but that's out of scope for this commit.

If you build with Visual C++ 2013 then three tests currently may fail with
Daylight Saving Time related problems: F<t/io/fs.t>,
F<cpan/HTTP-Tiny/t/110_mirror.t> and F<lib/File/Copy.t>. The failures are
caused by bugs in the CRT in VC++ 2013 which are fixed in VC++2015 and
later, as explained by Microsoft here:
L<https://connect.microsoft.com/VisualStudio/feedback/details/811534/utime-sometimes-fails-to-set-the-correct-file-times-in-visual-c-2013>. In the meantime,
if you need fixed C<stat> and C<utime> functions then have a look at the
CPAN distribution Win32::UTCFileTime.

If you build with Visual C++ 2015 or later then F<ext/XS-APItest/t/locale.t>
