Description soldatov 2008-09-04 10:30:33 UTC 
See /export/new_projects/perl-5.8.5/ext/SDBM_File/sdbm/sdbm.c file

Other test case:

#include <errno.h>

extern int errno; // <-- unexpected token: ;

int main(int argc, char** argv) {

    return (0);
}
Comment 1 Vladimir Voskresensky 2008-09-05 12:38:49 UTC 
This is the last syntax error in Perl, need to be fixed in 6.5
Comment 2 Alexey Vladykin 2008-09-08 10:19:33 UTC 
errno is a macro. After expansion we get the following declaration causing parser error:
extern int (*__errno_location ());

See IZ#87792: Parser reports error on declarations with name in parenthesis.
