Subject: [PATCH] build: AC_USE_SYSTEM_EXTENSIONS in configure.ac.
|
||||
|
||||
This would, e.g. define _GNU_SOURCE in config.h, enabling the
|
||||
reallocarray() prototype in glibc 2.26+ on Linux systems with that
|
||||
version of glibc.
|
||||
|
||||
Fixes #241.

Subject: [PATCH] build: make it possible to disable the build of the flex
|
||||
program
|
||||
|
||||
The flex program uses fork(), which isn't available on noMMU
|
||||
systems. However, the libfl library does not use fork(), and be used
|
||||
by other programs/libraries.
|
||||
|
||||
Therefore, it makes sense to provide an option to disable the build of
|
||||
the flex program.
