Subject: * dcrt0.cc (dll_crt0_1): Move uinfo_init call to before sigproc_init to avoid a
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=541cdc15f129aba28ec7f0afb54b5e79b200c94b;p=pf3gnuchains%2Fpf3gnuchains3x.git

* dcrt0.cc (dll_crt0_1): Move uinfo_init call to before sigproc_init to avoid a
race.
(noload): Add an extra argument for debugging.
* uinfo.cc (uinfo_init): Eliminate test for multiple calls.
(getlogin): Assume that uinfo_init has already been called.
