From 4326da204f9df312ed54892e2e1e356cae1972f7 Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Sun, 9 Apr 2017 10:10:28 +0200 Subject: [PATCH] Makefile: comment tricky yconf condition The yconf.c file is generated from the yconf.y yacc source; it is the main and only source file that is actuall compiled, as it #include-s the other source files (weird, but that's how it's done upstream). So yconf.c does not need to be listed as a built source; the other two, generated from lex and gperf source files, do need to be listed because they are not part of _SOURCES, but are only in _EXTRA_SOURCES. However, .c files generated from yacc code are nt considerate as being intermediate files, and thus are not cleaned automatically. Signed-off-by: "Yann E.
