[fpc-devel] Proposal to adapt search patch under Haiku using a target specific option (-WH).

[Pierre Muller]

  Hi Olivier,

if you want, I can integrate those changes into trunk for you.

 Did you already start working on other CPU support for Haiku?

 Do you have any compile-farm similar to gcc-farm?

 It would be nice to also get regular testsuite results for Haiku OS!


Have a nice new year celebration!

Pierre

PS: I don't remember if you speak French,
but, just in case,
Bonne et heureuse année
else
Happy New Year!
