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]

Yes, it does, thank you.

I'm still seeing a bunch of warnings:

 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]

Closing this out as build has been fixed.

Thank you again.
