missing module dependencies for vasnprintf

[Jarno Rajahalme]

Hi,

modules/vasnprintf is missing dependencies, which results in compile error:

vasnprintf.c:103:28: error: isnanl-nolibm.h: No such file or directory
vasnprintf.c:104:20: error: fpucw.h: No such file or directory
vasnprintf.c:109:28: error: isnand-nolibm.h: No such file or directory
vasnprintf.c:110:27: error: printf-frexp.h: No such file or directory
vasnprintf.c:116:28: error: printf-frexpl.h: No such file or directory

I got rid of the errors with this change:
*** modules/vasnprintf~ Fri Apr  2 17:41:34 2010
--- modules/vasnprintf  Thu Apr  8 12:32:19 2010

+ isnanl-nolibm
+ frexp-nolibm
+ frexpl-nolibm
+ printf-frexp
+ printf-frexpl
+ 

 configure.ac:
 gl_FUNC_VASNPRINTF


I did not check the sources if these are enough in all cases...
