Inhibiting the transformation certainly improves the chances of colliding
with incompatible externals written in other languages--but that might be
intentional.

Names are changed this way for `f2c' compatibility.
Note that ( as far as I remember ) -fno-underscoring' inhibitis ALL
transformations, so you don't need `-fno-second-underscore'.
You need '-fno-second-underscore' only in case you want to have
underscoring enabled, but not the 'second' one.
