Hi,

I encountered problems with the call nan(NULL) in file trionan.c on our 
OSF1 (Tru64) V5.1A box. We use the C-Compiler V6.4 and CXX V6.3-014.
After making a patch to the system provided by Compaq the libm was
changed and now the program xmllint crashes with SEGFAULT within
the call nan(NULL). Unfortunately I dont know the id of the patch.

I made the following changes to the file trionan.c to get it work:

include <nan.h> // for dnan structure

In trio_nan function:

#if defined(TRIO_COMPILER_SUPPORTS_C99)

+++#ifdef TRIO_COMPILER_DECC
+++    dnan dnan_;
+++    result = nan(&dnan_);
+++#else
    result = nan(NULL);
+++#endif

#elif defined(NAN) && defined(__STDC_IEC_559__)

Lines with +++ signs were added.

Any ideas or comments?

Thank you
