[SunHELP] gd 2.0.33 ./configure failure

[listmail at triad.rr.com]

I'm trying to compile gd 2.0.33 on Solaris 8 with libpng 1.2.8 installed
and getting some error about png_create_read_struct and the config log
shows ld: fatal: option -dn and -P are incompatible, ld: fatal: Flags
processing errors. See below.  I'm not sure what to do at this point.
