+
+ * Makefile.am (AM_CFLAGS): enable compiler warnings.
+ * configure.ac: use AC_PROG_LEX instead of KPSE_PROG_LEX
+ because 'flex -l' produces bad code (at least with flex-2.5.35).
+
+ * lacheck.l: use ANSI C prototypes for all functions.
+ declare yywrap as static.
+ (g_checkend): add explict braces to avoid ambiguous `else'.

+2009-04-20 Peter Breitenlohner <peb@mppmu.mpg.de>
+
+ Adapt to TL2009 build system.

* configure.in: added AC_CONFIG_HEADERS (moved
