Subject: Also track directly imported modules in a separate list
X-Git-Url: http://git.demorecorder.com/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4270141a7cb3c68f50251be19a5a628aa18553e6;hp=d898fd39ad6c82207eb78666b2daad982dd757b5;p=free-sw%2Fxcb%2Fproto

Also track directly imported modules in a separate list

This allows the generated header files to only include the
directly referenced header files, with the indirectly referenced header
files included by the directly referenced ones.
