Subject: Update tcpdump-stdinc.h
X-Git-Tag: tcpdump-4.6.0~43^2^2~8
X-Git-Url: https://git.tcpdump.org/tcpdump/commitdiff_plain/4124bed500f41fcd2890fc85c24f3e49652bd0af

Update tcpdump-stdinc.h

Put WinPcap's header "bittypes.h" before potentially defining basic types like "uint8_t". Define EAFNOSUPPORT unless defined in system's <errno.h>. The local Win32/Include/errno.h is gone.
