[PATCH] 1.4.22 historical gcc compatibility

[Dario Niedermann]

The enclosed patch enables gnupg-1.4.22 to compile with gcc-2.95.3.

An accomplishment which - while probably not very high on most people's
priority lists - did allow me to build it on OpenBSD 3.3 (2001 vintage,
not quite ancient).

The patch is of my own doing and just removes what the old compiler
sees as a syntax error.

Regards,
Dario Niedermann
