Bug 37006

  There's a new candidate in http://httpd.apache.org/dev/dist/ ... which
  we hope will become the next release.  It contains some build fixes for
  AIX, could you give it a whirl and report back?

This is symptomatic of a bad gcc installation.  gcc's copy of selected system
header files were prepared for a different level of the OS, and a mismatch ensues.

There is some sort of fix-include procedure to rebuild gcc's copy of these
system header files.  google for that or ask whomever you got the gcc build from.

I tried the new version httpd-2.0.55 but still the same "pthread.h" errors and 
make is failing.

not a bug.

gcc version too old, get a GCC for aix 5.3  from 

http://www-03.ibm.com/servers/aix/products/aixos/linux/ezinstall.html

install gcc, gcc plusplus, c++ libs and c++devel libs and 
then the errors are gone.....
