Conflicting function definitions cause build failure

In mod_amf.tmpl (which is renamed mod_amf.h by the install script), a number of functions are declared with a single argument, e.g.

int checkIsMobile(char *userAgent);
int checkIsTablet(char *userAgent);

char *getOperativeSystem(char *useragent);
char *getOperativeSystemDesktop(char *useragent);
char *getOperativeSystemVersion(char *useragent, char *os);

However, in mod_amf.c, they are redeclared with multiple arguments:

int checkIsMobile(char *userAgent, const char *ch_ua_mobile)
int checkIsTablet(char *userAgent, const char *ch_ua_tablet)

char *getOperativeSystem(char *useragent, const char *ch_ua_platform)
char *getOperativeSystemDesktop(char *useragent, const char *ch_ua_platform)
char *getOperativeSystemVersion(char *useragent, char *os, const char *ch_ua_platform)

This results in the build failing.
