func_emit_cwrapperexe_src() with mingw32ce: errno does not exist

[Vincent Torri]

Hey,

in the function func_emit_cwrapperexe_src(), errno.h is automatically 
included. But errno system does not exist on Windows CE and that file does 
not exist.

can it be guarded with __MINGW32CE__ ?

errno is also used with LTWRAPPER_DEBUGPRINTF and with strerror in 
ltmain.sh. I think that these 2 calls must be guarded and something else 
should be displayed when migw32ce is used.

thank you
