[Spice-devel] [PATCH 2/4 v2] mingw: avoid problems for using %zd (C99)

[Fabiano Fidêncio]

Otherwise the following problem can be faced:
src/vscclient.c: In function 'connect_to_qemu':
src/vscclient.c:642:16: error: unknown conversion type character 'z' in format [-Werror=format=]
         printf("Connected (sizeof Header=%zd)!\n", sizeof(VSCMsgHeader));
                         ^
src/vscclient.c:642:16: error: too many arguments for format [-Werror=format-extra-args]
---
Changes since v1:
- Fix the host_os check
- Fix the (linux) compilation break
