Make it compile on cygwin in c++11 mode

When using -std=c++11, the cygwin compiler automatically defines
__STRICT_ANSI__ which is used as a guard for not declaring essential
unix standard calls such as setenv, popen, etc. As a result,
compilation stops with errors such as "xxxx has not been declared".
By undefining the guard, compilation succeeds and lyx works Ok.
