[CM] snd compilation problems on SGI

[Bill Schottstaedt]

This is caused by the SGI gettext support -- !%@#$#%@. Here's a quick
workaround -- in snd-utils.c at line 95, change the langinfo business to:

#if HAVE_LANGINFO_DECIMAL_POINT || HAVE_LANGINFO_RADIXCHAR
#undef MALLOC
#include <langinfo.h>
#undef MALLOC
#define MALLOC malloc
#endif

I'll try to add a check for this to the configure process.

Did configure define HAVE_SCM_MAKE_REAL?  (I'm guessing that it didn't
for some reason, but that in guile 1.5.4 scm_makdbl has been removed,
so the compiler is assuming it returns an int).
