Subject:	GCC package missing sanitize helper libraries
To:	cygwin AT cygwin DOT com

The cygwin gcc package appears to be missing the helper libraries for
the -fsanitize series of options.

$ gcc -fsanitize=address a.c
/usr/lib/gcc/x86_64-pc-cygwin/5.3.0/../../../../x86_64-pc-cygwin/bin/ld:
cannot find -lasan
collect2: error: ld returned 1 exit status

Ditto for -fsanitize=undefined (-lubsan), -fsanitize=thread (-ltsan),
and -fsanitize-leak (-llsan)

On my linux box, these libraries are at paths like
/usr/lib/gcc/x86_64-pc-linux-gnu/5.3.0/liblsan.so

Is this simply a packaging oversight, or are these flags broken on cygwin?

Thanks,

Peter Foley
