The configure script of ntbTLS 0.1.2 checks for dependency versions earlier than those actually needed.
- It looks for libgcrypt >= 1.6.0 but actually needs >= 1.7.0 (attempts to link with gcry_mpi_ec_decode_point which was added in 2016-01-28, released in 1.7.0)
- It looks for libgpg-error >= 1.17, but uses GPGRT_ATTR_PRINTF() macro added in 1.19. Would be trivial to stub and keep 1.17 as the required version if wanted. (libgcrypt only wants 1.13 so there is not a transitional need to bump it)

checking for GPG Error - version >= 1.17... yes (1.17)
Interface changes relative to the 1.19 release:
GPGRT_ATTR_PRINTF NEW macro.
util.h uses GPGRT_ATTR_PRINTF() macro, which was added in libgpg-error 1.19:
void _ntbtls_debug_msg (int level, const char *format,
...) GPGRT_ATTR_PRINTF(2,0);
