Subject: build: Mark files generated by lopsub as precious.
X-Git-Tag: v0.2.0~3^2~2
X-Git-Url: http://git.tuebingen.mpg.de/?p=osl.git;a=commitdiff_plain;h=0e23fd87097dd74a6b9e1a365c79716ec623e881;ds=sidebyside

build: Mark files generated by lopsub as precious.

Without this, running make(1) with no arguments after a previous
successful run would re-generate at least the .lsg.c file. This patch
avoids that.
