>Description:
When attempting to compile xf86ScanPci.c during the build of the xorg-server port, gcc grows to consume all memory and swap until killed.  As such Xorg 7.2 cannot be built on HEAD with gcc 4.2. I changed CFLAGS to use -O -fno-unit-at-a-time and it still crashes.  

> gcc -v
Using built-in specs.
Target: i386-undermydesk-freebsd
Configured with: FreeBSD/i386 system compiler
Thread model: posix
gcc version 4.2.0 20070514 [FreeBSD]

scanpci includes a list of all known PCI vendor and device numbers and strings and gcc probably has issues with dealing with so much static data.

Unfortunately other xorg-server components require scanpci code and so just removing scanpci from the build does not address the issue.
