[Bug libquadmath/68665] fails to link quad math functions even though cygquadmath-0.dll is present

--- Comment #5 from Robert Shuler <mc1soft at yahoo dot com> ---
I just did a from-scratch installation on a different computer (at the office)
with Win7 of cygwin-64 GCC and the quad math package.  The results are exactly
the same.  Built-in _float128 works, but identical error messages trying to use
the functions.  In this case, however THE DLLs ARE MISSING.

Here is result of trying -lquadmath on the office installation.

$ gcc -lquadmath -o test128a test128a.c
/tmp/ccEh0rVO.o:test128a.c:(.text+0x9f): undefined reference to
`quadmath_snprintf'
/tmp/ccEh0rVO.o:test128a.c:(.text+0x9f): relocation truncated to fit:
R_X86_64_PC32 against undefined symbol `quadmath_snprintf'
collect2: error: ld returned 1 exit status

That is what I'd expect given the missing dll's.  I'll try it on the WinXP
installation this evening and post the result here.
