Build regression on i386-mingw

[FX Coudert]

The following patch causes a build failure on i386-mingw:

2005-05-15  Gabriel Dos Reis  <gdr@integrable-solutions.net>
         * fixincl.c: #include <sys/wait.h>

Build was successful before, but now fails when compiling fixincl.c, 
since MinGW doesn't have a sys/wait.h headers file. With this #include 
statement removed, build is successful.

Filed in bugzilla as PR 21683.

Thanks for fixing it,
FX
