Again, this is hopefully addressed by my 20170627121718.12078-2-avarab@xxxxxxxxx ([PATCH 1/3] sha1dc: update from my PR #36). > A third option is to compile a small test and just -DSHA1DC_BIGENDIAN in > the Makefile. This would be ideal, but so far the only facility we have for that is the configure script, which there have been objections to making a hard dep in the past, thus we have various bits done via macros that would be better done via built-time compiling & testing a C program. My memory of such discussions is hazy though, did people fundimentally object to the idea, or was it just an objection to autoconf in particular, I don't know. If it was just autoconf maybe someone more clever at Makefile magic than me could come up with a way to compile a test program that would then define a flag that would be passed to the rest of the programs, and set up dependencies in such a way that it was done before anything else, I don't know if that's easy/possible with make.
