#70 MINGW32 has no sincos

[T.Tamaki]

in ltiSinCos.h,
#if defined(_LTI_GNUC_3) && !(defined(_LTI_MACOSX))

but above can not be compiled with mingw32, so the
following works:

#if defined(_LTI_GNUC_3) && !(defined(_LTI_MACOSX)) &&
!(defined(_LTI_CYGWIN))

I don't check, but cygwin and mingw may not have sincos.

in 1.9.15 and ltilib1 cvs. no sincos in litlib2 cvs?

As suggested by Mingw users list, the following function
might be implemented.

#if (defined(_LTI_CYGWIN))

void inline sincos_impl(double angle, double& sval,
double& cval)
{
double ss,cc;
__asm__ ("fsincos;" : "=t" (cc), "=u" (ss) :
"0" (angle));
sval=ss;
cval=cc;
}

#endif
