9a895bedde Fix "error "SSSE3 instruction set not enabled" when compiling using GCC version < 4.9 without -mssse3 option (SSSE3=1 when using make). (#507) 
Compiling with -mxxx defines the corresponding macro of the intrinsics.
For example, -mssse3 defines __SSSE3__ macro to 1.

In GCC versions < 4.9, it is not possible to use and call x86 intrinsics only at runtime without
compiling the entire file with the -mxxx option.

For example, if we want to call SSSE3 intrinsics without compiling with -mssse3, the macro __SSSE3__ is not defined.
Therefore, when including <tmmintrin.h>, this results in "error "SSSE3 instruction set not enabled"" because of :
	#ifndef __SSSE3__
	# error "SSSE3 instruction set not enabled"
Since GCC 4.9, this has been fixed and it is possible to call x86 intrinsics from select functions in a file
that are tagged with the corresponding target attribute without having to compile the entire file with the -mxxx option.
This can be seen in <tmmintrin.h> which in recent versions (>= 4.9) contains :
	#ifndef __SSSE3__
	#pragma GCC push_options
	#pragma GCC target("ssse3")
	#define __DISABLE_SSSE3__

Since SSSE3 is only used under Windows for ChaCha256, this can be fixed by preceding '#include <tmmintrin.h>' with
#if defined (_MSC_VER) && !defined (TC_WINDOWS_BOOT).

See https://gcc.gnu.org/gcc-4.9/changes.html

0d91dab5b9 Align section types of Whirlpool_C and SHA256_K (#479) 
in order to fix LTO linking.

After switching to LTO for openSUSE Tumbleweed, veracrypt build failed with:
[  185s] ../Crypto/Whirlpool.c:105:45: error: 'Whirlpool_C' causes a section type conflict with 'SHA256_K'
[  185s]   105 | CRYPTOPP_ALIGN_DATA(16) static const uint64 Whirlpool_C[8*256+R] CRYPTOPP_SECTION_ALIGN16 = {
[  185s]       |                                             ^
[  185s] ../Crypto/Sha2.c:321:34: note: 'SHA256_K' was declared here
[  185s]   321 | CRYPTOPP_ALIGN_DATA(16) uint_32t SHA256_K[64] CRYPTOPP_SECTION_ALIGN16 = {
[  185s]       |                                  ^
[  185s] lto-wrapper: fatal error: g++ returned 1 exit status

Aligning section types of Whirlpool_C and SHA256_K fixes this.
