Description
Summary of the bug:
FFmpeg failed to build libavutil/avsscanf.c(42): error C2061: syntax error: identifier 'off_t' when build with VS2017 on Windows. This issue can be first reproduced from master revision 4b30726. I think 'off_t' type maybe undeclared. Could you please help take a look at this? Thank you!
Steps to reproduce:
1.git clone https://github.com/FFmpeg/FFmpeg.git D:\FFmpeg\src
2.Open a VS 2017 x86 prompt and browse to D:\FFmpeg
3.set FFMPEG_TARGET=i386
4.set FFMPEG_SRC_PATH=D:\FFmpeg/src
5.set FFMPEG_FATE_PATH=../fate-suite/
6.set PATH=D:\FFmpeg\tools;%PATH%
7.set MSYS2_PATH_TYPE=inherit
8..\tools\msys32\usr\bin\sh.exe --login -i -c "/D/ffmpeg/tools/build.sh"
