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). |
