[Paul Eggert]

branch: master
commit ab871981125393d89202932284eda6e507bfc6fd
Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>

    Port better to non-IEEE platforms
    
    * src/lread.c (string_to_number) [!IEEE_FLOATING_POINT]:
    Do not use the INFINITY macro, since the C standard requires
    it to provoke a compile-time error on platforms that do not
    support infinities.
