637629b31c8f74445525e17e2dd3b0f6e0a74415 convert skcms to c++
The main thing we do here is add a 'c' to the skcms source path.
The rest is build system updates and little language tweaks.
I have had to explicitly set -ffp-contract=off in GCC. Switching
from C11 to C++11 changed the default -ffp-contract from "off" to
"fast", which generates FMAs in places we don't want them. This
behavior is rooted in this lovely piece of code:
/* ISO C restricts floating-point expression contraction to within
source-language expressions (-ffp-contract=on, currently an alias
for -ffp-contract=off). */
if (flag_iso
&& !c_dialect_cxx ()
&& (global_options_set.x_flag_fp_contract_mode
== (enum fp_contract_mode) 0)
&& flag_unsafe_math_optimizations == 0)
flag_fp_contract_mode = FP_CONTRACT_OFF;
