[PATCH] Microsoft Visual C patches

[Andrei Errapart <andrei-VvktuG2w+SIZux3j3Bed6fC9HSW9iNxf@public.gmane.org>]

[-- Attachment #1: Type: text/plain, Size: 885 bytes --]

Hallo,


The attached patches are the result of compiling the dtc with the 
Microsoft Visual C (MSVC) in order to be able to run the dtc under 
Microsoft Windows.

Short descriptions of the patches:
checks:		MSVC is unable to handle 0-sized array literals.
fopen:		Binary files should be opened in binary mode.
signed-char:	For MSVC, char defaults to signed char.
dtc-header:
   1) Variadic macro in the form "args..." is a GCC extension.
   2) MSVC requires 0 to be present in a struct literal.

On a Linux, all tests pass when these patches have been applied.

We have been using the dtc on Windows computers for a few days and 
haven't had any problems so far. In the case people are interested in 
having the MSVC project file(s) and the few lightweight compatibility 
functions required for compilation, let me know and I can clean them up 
for public use.


best regards,
Andrei
