Bugzilla Bug 118264

While recompiling my system with gcc-4.0.2, I encountered a compile problem
with app-text/tetex-2.0.2-r5:

This problem seems to occur with gcc-3.4 as well, which seems odd. The fix is a
one-liner though, and is attached in the next message.

Patch for dvi-draw.c compile error

I can't make it fail with neither gcc-3.4.5 nor gcc-4.0.2!
Can you please re-sync and try again once more?

I have the same error with gcc-3.4.4 on a new install.

I can confirm that the patch works with gcc-3.4.4 and tetex-2.0.2-r5

tetex-2.0.2-r5 compile failure log

After re-syncing, I recompiled tetex and logged the compilation. It failed
again without the patch, but with the patch it works fine.

Fixed in CVS. Thanks for the report and the patch.
