Indeed, configure turn PL_DOUBLE on by default (unless you specify
--without-double), so that the fragment in file include/plConfig.h.in:

    /* Define if you want PLplot's float type to be double */
    #undef PL_DOUBLE

becomes, in file include/plConfig.h:

    /* Define if you want PLplot's float type to be double */
    #define PL_DOUBLE

If, as you reported, the file include/plConfig.h has "#undef PL_DOUBLE" then
PLFLT will be set to "float" in plplot.h (at line 126), unless there is a
weird bug hidden somewhere.

Could you please run the following and send the output to us:

    ./configure >/dev/null 2>&1
    grep PL_DOUBLE include/plConfig.h*
