Subject: [compile fix] Remove incorrect forward-declaration of perror().
X-Git-Tag: cln_1-3-7~34
X-Git-Url: https://www.ginac.de/CLN/cln.git//cln.git?a=commitdiff_plain;h=721eb0d4a24c50f765d01a33ec6d5619359c0f35;p=cln.git

[compile fix] Remove incorrect forward-declaration of perror().

First of all, the return type is void, not int (according to C89).
Secondly, perror is required by C89, so there's no need to check for it.

Fixes (cross-) compilation with MinGW.
