In ISO C, function pointers can be compared for equality with == but not the < > operators are not defined for them.   Therefore this operation is not allowed by the native C compiler on DEC Alpha OSF/1:

cc -std -DHAVE_CONFIG_H -I. -I.. -I../gnulib/lib -I../lib -I../gnulib/lib -I../intl \
       -DLOCALEDIR=\"/usr/local/share/locale\"  -I/usr/local/include  -ieee \
       -I/usr/local/include -c tree.c
cc: Error: tree.c, line 980: In this statement, "pl1->fn" and "pl2->fn" cannot be compared with a relational operator. (norelational)
     assert(pl1->fn <= pl2->fn);
cc: Error: tree.c, line 995: In this statement, "pc1->fn" and "pc2->fn" cannot be compared with a relational operator. (norelational)
 else if (pc1->fn > pc2->fn)
make[3]: *** [tree.o] Error 1
