+Subject: [PATCH] scanner: Include flexdef.h at %top block of scan.l
+
+config.h may define macros that alter the API of the standard library
+funtions, and so it should be included before any other standard

+
+For example: config.h may #define _GNU_SOURCE that would expose the

+include <stdlib.h> before config.h, reallocarray() would not be

+due to header guard.
+
+For now our config.h might `#define malloc rpl_malloc` -- this
+substitution must work before including stdlib.h, or else the compiler
+will complain about missing prototypes, and may result in incorrect
+code in scan.l (gcc warning: return makes pointer from integer without

+Subject: [PATCH] scanner: Fix glibc features.h dependency in skeleton.
+
+Commit a17d79e9c722a6735b6d2a8f152287404f27df32 defines _POSIX_C_SOURCE
+to the minimum of 1 if it's not defined in the user's scanner code or
+the compiling environment. However in glibc the macros are not yet set
+up until one of the libc headers is included. This unfortunately have
+made us overwrite the default _POSIX_C_SOURCE value that would be
+defined by glibc (200809L at the time of writing), causing regressions
+in user code.
+
+Now in this patch:
+1. Ensure feature test macros have been set up in glibc before checking
+or defining any of them in our skeleton code.
+2. Have a more conservative logic when determining the need to define
+_POSIX_C_SOURCE (required for fileno()).
+
+Fixes: #313
+
+Note:
+It could be tricky for application code to ensure feature test macros
+have been set up in glibc, since <features.h> is no portable header and
+not meant to be included directly by applications. The way to do it is
+to include a libc header which in turn includes <features.h>. However,
+many of the glibc headers check __USE_POSIX (a glibc internal macro
+defined if _POSIX_C_SOURCE is defined) and determine which interfaces
+to expose already, making the headers inappropriate for our goal.
+Those which don't depend on _POSIX_C_SOURCE, and are also available
+since ANSI C89, are only <assert.h>, <errno.h> and <math.h>.
+
+<assert.h> is finally favored due to other considerations:
+- <math.h> check for __USE_XOPEN in glibc, making a dependency on
+_XOPEN_SOURCE, besides it exposes much more interfaces than we need.
+- In djgpp, <errno.h> depends on _POSIX_SOURCE to hide definitions of
+some errno values when it's defined.
+- <assert.h> exposes the fewest interfaces among the 3 headers and, at
+the time of writing, checks for only C99 (for __func__), C11 (for
+_Static_assert), and _GNU_SOURCE when needed.
