I used a trick and my config.h.in had two lines:

#undef DEF
...
#define DEF(x)

And autoconf-2.59 did not touch "#define DEF(x)".  If it is allowed to
specify only #undef lines in config.h.in, then my trick was wrong.

May be more strict description (using words "must have only" or
"must contain only") about what is allowed in config.h.in should be
given in "Configuration Headers Templates".
