[Libguestfs] [PATCH 1/2] Include <config.h> at the start of every C file.

From: "Richard W.M. Jones" <rjones(a)redhat.com&gt; As a rule of thumb, every C file should begin with: #include <config.h> Also add AC_USE_SYSTEM_EXTENSIONS to configure.ac so that config.h defines _GNU_SOURCE etc when necessary. --- configure.ac | 3 +++ src/gpt.c | 2 ++ src/ldm.c | 2 +- src/ldmtool.c | 2 +- src/mbr.c | 2 ++ test/ldmread.c | 2 ++ test/partread.c | 2 ++ 7 files changed, 13 insertions(+), 2 deletions(-) diff --git a/configure.ac b/configure.ac index cbffa95..ff1b10e 100644 --- a/configure.ac +++ b/configure.ac @@ -32,6 +32,9 @@ AC_CONFIG_MACRO_DIR([m4]) AC_PROG_CC_C99 LT_INIT +# Define _GNU_SOURCE etc. +AC_USE_SYSTEM_EXTENSIONS + AC_CHECK_LIB([readline], [readline], [], [AC_MSG_ERROR([readline library is missing])]) diff --git a/src/gpt.c b/src/gpt.c index beb8711..7f89631 100644 --- a/src/gpt.c +++ b/src/gpt.c @@ -15,6 +15,8 @@ * along with this program.
