[libredwg] MSVC support?

[Ivan Radic]

Hi,

I have tried to compile using Microsoft Visual C++ Express and if you
decide to support it you will need to write C89 code.

Also in dwg.spec:
DWG_OBJECT(RASTERVARIABLES);
-  BITCODE_BL (class_version);
-  BITCODE_BS (display_frame);
-  BITCODE_BS (display_quality);
-  BITCODE_BS (units);
+  FIELD_BL (class_version);
+  FIELD_BS (display_frame);
+  FIELD_BS (display_quality);
+  FIELD_BS (units);

is this correct change or not?

Currently there are small changes to make it compile under msvc but
obviously this will change in the future...
If you need patch please advise how to send it ("git diff
master..HEAD" is available)...

Bye
