error: syntax error before "_X_SENTINEL"

[Chris H.]

Hello,
I just recenlly found that I am almost always unable to
build X (Xorg) related applications on a 5.5 box that has
pretty recent source. The applications all die during the
make process with the following error:
error: syntax error before "_X_SENTINEL"
Any to fix this? Googling indicates that this is a common
problem without a solution.

System runs Xorg 6.9.

Thank you for all your time and consideration.
