dnl sjl: this version of ncx.m4 has SX-specific optimisations as per
dnl Harveys mods to earlier versions. However, I have removed
dnl support for FLOAT2 and attempted to tidy up the mods to
dnl reduce the complexity a bit
dnl
dnl This is m4 source.
dnl Process using m4 to produce 'C' language file.
dnl
dnl If you see this line, you can ignore the next one.
