I think the problem are options like -g or -m64 and the like which
you also want to give to the linker on some systems, so it is quite
common and I'd say recommended to have the compiling stage get
CPPFLAGS and CFLAGS and the linking stage getting CFLAGS and LDFLAGS
(and link using the compiler, otherwise you might miss libraries anyway).
I do not know if automake started with this, or if it is older.

Huh? Never heared of that bug, it must be more than 15 years ago. Are
you sure it was not CFLAGS it passed to the linker?
