There has been no work done to make TinyCC emit valid ARM PEs.
It just compiles because there are no ELF specific parts in the ARM backend.

FPA - use the old FPA floating point instructions
VFP - use the new VFP floating point instructions
LD - long doubles are 12 bytes instead of 8
EABI - try to conform to the ABI specification written by ARM

Because it is the default on Linux (it has a FPA emulator).

Did you read the text I put there where you downloaded libtcc1.a?

Probably.
I have once used binutils to successfully disassemble an ARM PE.
You might have luck finding out what has to be changed in there.

Which C library do you indend to use on WinCE?
