From: Johannes Sixt <j6t@xxxxxxxx>
compat/regexec.c had a weird combination of function declaration in ANSI
style and function definition in K&R style, for example:
static unsigned
re_copy_regs (struct re_registers *regs, regmatch_t *pmatch,
int nregs, int regs_allocated) internal_function;
static unsigned
re_copy_regs (regs, pmatch, nregs, regs_allocated)
struct re_registers *regs;
regmatch_t *pmatch;
int nregs, regs_allocated;
{ ... }
with this #define:
#ifndef _LIBC
# ifdef __i386__
# define internal_function __attribute ((regparm (3), stdcall))
# else
# define internal_function
# endif
#endif
The original version as shown above was fine, but with the ANSIfied
function definition and in the case where internal_function is not empty,
gcc identifies the declaration and definition as different and bails out.
Adding internal_function to the definition doesn't help (it results in
a syntax error); hence, remove it from the subset of declarations that gcc
flags as erroneous.

Here's a fix.
