Failed Build - Xorg GIT packages

[snake plisken]

libX11, libXfonts complain about no defines for 0_RDONLY  

I had to manually add an #include for fcntl.h to the individual source
files causing the problems.
  
For libXfonts: libXfont/src/fontfile/fileio.c 
For libX11: libX11/modules/im/ximcp/imLcIm.c

I believe several other packages had problems as well.

Build system:
Slackware 12.2 
GCC 4.2.4
