Never attach anything to a usenet article, especially a binary.
This is a text only medium.
In addition, pragma is not sanctioned by the standard. From N869:
[#1] A preprocessing directive of the form
# pragma pp-tokens-opt new-line
where the preprocessing token STDC does not immediately
follow pragma in the directive (prior to any macro
replacement)136) causes the implementation to behave in an
implementation-defined manner. The behavior might cause
translation to fail or cause the translator or the resulting
program to behave in a non-conforming manner. Any such
pragma that is not recognized by the implementation is
ignored.
