Hello,

I find myself unable to compile trunk (r36201) caused by errors in process.c (execve):

compiling ../process.c
../process.c: In function 'proc_exec_cmd':
../process.c:1138:9: warning: passing argument 2 of 'execve' from incompatible pointer type [enabled by default]

Above error happens under GCC 4.5.2, 4.6.1 and 4.6.3 in both x86 and x64 (mingw and mingw-w64 respectively)

Base Ruby is 1.9.3-p194 [i386-mingw32]

Oops. I hope r36202 fix the problem.

Yes, it does, thank you.

I'm still seeing a bunch of warnings:

Closing this out as build has been fixed.

Thank you again.
