[Tinycc-devel] tinycc test failure on 32-bit Linux

[Ramsay Jones]

Hi Michael,

I occasionally build/test tcc on 32-bit Linux. Recently, a test failed
which bisected to commit 1fd3709379 ("Fix local extern vardecl",
2019-03-18). Viz:

  $ uname -a

  $ ./tcc -v
  tcc version 0.9.27 (i386 Linux)

The 98_al_ax_extend test does not run on x86_64.

Just an FYI. Thanks!
