Hi,

I just attempted to update from 7.56.1 to 7.57.0 on a Linux CentOS 4.8 using gcc 4.8.5 but am now running into compile errors as below when compiling curl with the following configure command:

./configure LDFLAGS="-L"${libraryRoot}" -ldl" --prefix=${installDir} --with-ssl=${libraryRoot} --disable-ldaps --disable-ldap
--without-libidn --without-libnss --enable-shared=no --enable-ares=${libraryRoot}/cares

The lines in in.h are the following

extern uint32_t ntohl (uint32_t __netlong) __THROW __attribute__ ((__const__));
extern uint16_t ntohs (uint16_t __netshort)
     __THROW __attribute__ ((__const__));
extern uint32_t htonl (uint32_t __hostlong)
     __THROW __attribute__ ((__const__));
extern uint16_t htons (uint16_t __hostshort)
     __THROW __attribute__ ((__const__));

Was there an intentional drop in backwards compatibility in 7.57.0 ?
