Similar problem with cygwin 1.3.11-3 and libxml2 2.4.22. From configure'ing
libxml2, the included TRIO shouldn't be needed. But make'ing, there are a
couple of unresolved symbols from libxml2's trionan.c, because of references
to fpclassify and signbit.

These are now defined as macroes in /usr/include/math.h:

#define fpclassify(x) \
          (__extension__ ({__typeof__(x) __x = (x); \
                           (sizeof (__x) == sizeof (float))  ?
__fpclassifyf(__x) : __fpclassifyd(__x);}))

#define signbit(x) \
          (__extension__ ({__typeof__(x) __x = (x); \
                           (sizeof(__x) == sizeof(float)) ? __signbitf(__x)
: __signbitd(__x);}))

As far as I can see, __fpclassifyf, __fpclassifyl, __signbitf, and
__signbitl can be found in /lib/libmingwex.a, but __fpclassifyd and
__signbitd are nowhere to be found.

A temporary solution might be to force use of included TRIO sources, so that
trio_fpclassify and trio_signbit are used rather than fpclassify and
signbit.

Kind regards
Peter Ring

It seems to me that guile 1.4.1 will not build with current cygwin 
libraries due to the lack of the symbol fpclassifyd. As far as I can 
make out this seems to be some problem with current version of cygwin.
