Changed paths:
M Configure
M Cross/cflags-cross-arm
M cflags.SH
Log Message:
-----------
Teach Configure and cflags.SH about C99
Probe to see whether we need -std=gnu99 or -std=c99 to get C99 code to
compile. In cflags.SH, remove code that added gcc warning flags that were
compatible with C89 but are not compatible with C99.

Changed paths:
M Configure
Log Message:
-----------
Test declarations after statement in Configure's C99 probe code
Also ensure that the relevant failure error message is output even with
Configure's -s flag, as we shouldn't stay silent for a message that causes
Configure default to aborting.
With these changes, Configure will fail the C99 probe test if passed
-Accflags="-Werror=declaration-after-statement" or
-Accflags="-Werror=long-long"

Changed paths:
M cflags.SH
Log Message:
-----------
cflags.sh should not add -std=c99 if -std=gnu99 is already set
Having both looks like it ought to cause the build to fail, as with -std=c99
second it will override any previous -std=gnu99, and some platforms need the
former to both compile C99 code and have correct includes during Configure
probing.
However testing on those platforms without this change doesn't show any
errors. So this change doesn't seem to strictly be necessary. But it does
prevent our generated compiler command lines having contradictory flags,
and hence looking daft.

Log Message:
-----------
Note how best to confirm that other C99 features can be relied upon
If C99 functionality can't be emulated on platforms which don't provide it,
then one really needs to test whether MSVC and the VMS compiler support it.

Log Message:
-----------
Update README.win32 to the new C99/MSVC 12.0 requirements
* Remove specific notes related to Microsoft Visual C++ 2005 Express Edition
and earlier
* Visual Studio 2013 is the only version that still has Express edition (in
addition to Community), so simplify the text by only mentioning Community
* Remove the reference to IA64, and mention x86_64 along with x86
* In the context of x86_64, clarify that mingw's binaries can run on both
* Update the URL for mingw

Changed paths:
M inline.h
Log Message:
-----------
Introduce a "declaration after statement" into inline.h
The core now permits some C99 code, so extensions need to ensure that any
C compiler flags they add or change permit C99 code.
This code is inlined by XS extensions in the core and on CPAN. The intent
is that this commit should show up for any failure bisection, making it
obvious what the cause is, and what the fix needs to be.
