Details:

With autoconf 2.67 a use of AX_CFLAGS_GCC_OPTION() like this

+verabtim+
    AX_CFLAGS_GCC_OPTION([-fvisibility=hidden], AM_CFLAGS)
-verabtim-

with an option containing a non-literal character like = suddenly breaks.
This was due to directly accessing variables defined with AS_VAR_PUSHDEF(),
rather than using AS_VAR_SET() and AS_VAR_COPY().

----

I am no m4 hacker, so I do not guarantee my changes are correct, but I do get
the expected result both with autoconf 2.65 and autoconf 2.67 after my
changes.

Also, I did not update the #serial as I assume this is done automatically.
