that'll be useful |

I think that makes sense, (I'm tempted to kill the stupid warning |
| 22 |
append-ldflag issues when using it with -l*, it's a false warning for |
| 23 |
--as-needed users anyway... you won't add a lib if the link doesn't |
| 24 |
fail...) |

Is it possible to: |
| 37 |
a) make many separate packages (for each function, or function group its |
| 38 |
own) in a new catagory, or |
| 39 |
b) make use of EAPI 2_pre1, and have a zillion of USE flags on the |
| 40 |
gnulib ebuild and have each ebuild that requires gnulib to depend on the |
| 41 |
USE-flag corresponding the function is enabled. |
| 42 |
|
| 43 |
The first results in a huge list of packages, with a little problem to |
| 44 |
make it a single libgnu.a again (but a wrapper script should do), the |
| 45 |
second results in a recompilation of gnulib probably for many times just |
| 46 |
to add the missing functions. |
