[Chicken-users] Solaris 10 / SPARC - missing isinf

[Claude Marinier]

Hi,

Building chicken 4.7.0 on Solaris 10 running on SPARC (M5000) with gcc 
3.4.6 from SunFreeware.

Linking chicken fails with missing isinf. Added definition to chicken.h 
after line 954.

    #define C_isinf(f)                 isinf(f)"

Found definition on autoconf web site. See below.

A better solution is needed.

Thanks.
