Errors on std headers

[nazzrim]

I want to create a wrapper for cimgui but wasn't able to get c-for-go to run.

I am using a win10 x64 machine with mingw64.

Here are some commands I tried and the corresponding output:

c-for-go -out . cimgui.yml

too many errors

I thought this may be related to #49 and was wondering if this would work on linux. So I set up a Ubuntu 18.04.3 LTS vm, installed cland, and tried it again.

I got similar errors regarding missing header files (/usr/include was set as include path) and when I tried with --ccincl --ccdefs I got the following error:

cimgui.h@898:44 unexpected identifier vec, expected one of [')', ',', ...]

The error corresponds to this line:

inline ImVec2_Simple ImVec2ToSimple(ImVec2 vec)

[nazzrim]

I was able to fix the above error on my windows machine with the following defines.

  Defines:
    __builtin_va_start: {}
    __builtin_va_end: {}

But sadly I now get the same error as on unix:

processing .\cimgui.yml ⠙[ERR] cimgui\cimgui.h:898:44: unexpected identifier vec, expected one of [')', ',', ...]

Thanks, this will be incorporated in a patch
