Hello,

I'm not sure about __FLOAT_WORD_ORDER__
but I guess __ORDER_PDP_ENDIAN__ can be added right away like so:
Many things do exist in GCC, and many of them could be easily
added to TCC, but for what reason in practice?
For example you can do a research on __ORDER_BIG_ENDIAN__in the
tinycc commits and will find that is was first added in
https://repo.or.cz/tinycc.git/commitdiff/9712aff9c00ecf24adc89f42aa674ede4e35137d
libtcc.c:
- Add some defines for gcc testsuite (only most common)
According to that the author found that the ability to run the
gcc testsuite has some practical relevance because it can help
to improve tinycc, and he also made a decision what to add and
what not "(only most common)".

Is this OK?
