Problems configuring on Mac OS X

[Yann Michel]

Hi,

I just downloaded readline-5.0 and tried to build it on Mac OS X. 
Unfortunately the configure gave me a warning:

checking stdarg.h usability... no
checking stdarg.h presence... yes
configure: WARNING: stdarg.h: present but cannot be compiled
configure: WARNING: stdarg.h: check for missing prerequisite headers?
configure: WARNING: stdarg.h: proceeding with the preprocessor's result
configure: WARNING:     ## ------------------------------------ ##
configure: WARNING:     ## Report this to address@hidden ##
configure: WARNING:     ## ------------------------------------ ##
checking for stdarg.h... yes


The later make fails, too.

I hope you could help me with that.

Thanks in advance.

Regards,
Yann
