Re: [Tinycc-devel] cross-compilation of tcc fails

[Pip Cet]

Can you try "git revert 1cbb4d3" to see whether that fixes the
problem? Alternatively, you can try compiling with "make
XCC=arm-openwrt-linux-muslgnueabi-gcc".

In general it looks to me like the slew of commits starting on March 3
could do with some further review.
