Always inline sysdepCallMethod if gcc supports always_inline attribute

2004-06-22  Dalibor Topic  <robilad at kaffe.org>

        * configure.ac:
        Check for always_inline attribute.

        * configure,
        config/config.h.in:
        Regenerated.

        * config/arm/sysdepCallMethod.h,
        config/i386/sysdepCallMethod.h,
        config/ia64/sysdepCallMethod.h,
        config/m68k/sysdepCallMethod.h,
        config/parisc/sysdepCallMethod.h,
        config/powerpc/sysdepCallMethod.h,
        config/s390/sysdepCallMethod.h,
        config/superh/sysdepCallMethod.h,
        config/x86_64/sysdepCallMethod.h:
        (sysdepCallMethod) Always inline if gcc supports it.

        * m4/gcc_attribute.m4:
        Added check for always_inline attribute.
