[Plplot-devel] AC_CHECK_FUNC(isnan,... fails

[<jc...@fe...>]

Hi,

AC_CHECK_FUNC(isnan, ...
or
AC_CHECK_FUNCS(isnan isinf finite)

fails to detect isnan,... under OSF, as these functions are in libm and 
configure don't add -lm to the compile command.
isnan() and finite() are declared in math.h in this system.

 Is there a fast cure for this?

Thanks,
Joao
