Nice try, but this does not cut it ;). |

For one thing that function is gcc version agnostic. For example it will |
| 8 |
permit certain -march combinations which are only supported by >=gcc-3*. |
| 9 |
On the other hand it may be too restricitve in general, by only allowing flags |
| 10 |
listed on some (very small) list. |
| 11 |
|
| 12 |
The function (or alternatively two - three functions containing corresponding |
| 13 |
gcc version in the name) to fit the bill perfectly should only strip |
| 14 |
unsupported flags for the specified version, "correcting" them where |
| 15 |
possible. |
| 16 |
Thus, for example: |
| 17 |
-march=i686 will be permitted, but |
| 18 |
-march=pentium3 will get changed to -march=i686, and |
| 19 |
-mfpmath=* will get stripped, etc. |
| 20 |
while keeping other flags intact.. |
| 21 |
|
| 22 |
Of course in a very pedantic situation both function could be applied in turn |
| 23 |
yielding converted and (then) stripped flags .. |
