@ -57,6 +57,10 @@ porting:
Cedril Priscal ported socat to Android (using Googles cross compiler).
The port includes the socat_buildscript_for_android.sh script
added check for component ipi_spec_dst in struct in_pktinfo so
compilation does not fail on Cygwin (thanks to Peter Wagemans for
reporting this problem)
