    AX_CFLAGS_GCC_OPTION: bumped serial number

commit 62b7140eed87a2d4df84f23149f05f37663fef07
Author: Peter Kjellerstedt <address@hidden>
Date:   Wed Aug 25 13:55:45 2010 +0200

    AX_CFLAGS_GCC_OPTION: Use an actually existing gcc option as example

commit acb306ce125b3e7d6df709940fc0d159ab35cf11
Author: Peter Kjellerstedt <address@hidden>
Date:   Wed Aug 25 13:52:09 2010 +0200

    AX_CFLAGS_GCC_OPTION: Correct handling of indirectly named sh vars
    
    With autoconf 2.67 a use of AX_CFLAGS_GCC_OPTION() like this
    
        AX_CFLAGS_GCC_OPTION([-fvisibility=hidden], AM_CFLAGS)
    
    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().
