Avoid breakage with gcc 5
|
|
|
|
* src/Makefile.am: Add -P to the C preprocessor when building
|
|
mkerrcodes.h, to avoid a noisy intermediate pipeline.

With gcc 5 without this patch, we see many errors like the following:
|
|
|
|
gcc -I. -I. -o mkerrcodes ./mkerrcodes.c
|
|
In file included from ./mkerrcodes.c:26:0:
|
|
./mkerrcodes.h:9:5: error: expected expression before ‘,’ token
|
|
{ , "GPG_ERR_E2BIG" },
|
|
^
|
|
./mkerrcodes.h:10:5: error: expected expression before ‘,’ token
|
|
{ , "GPG_ERR_EACCES" },
|
|
^
|
|
|
|
This patch cleans up the generated mkerrcodes.h by making the
|
|
intermediate stage clean for all the versions of gcc i tested (4.x and
|
|
5).
