Subject: Fix compilation warning in the MinGW build
X-Git-Tag: emacs-26.0.90~1840^2~18
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=d0e1774a5850b924915bde5abefe791ce18d84a2;p=emacs.git

Fix compilation warning in the MinGW build

* nt/inc/ms-w32.h: Include stdint.h.
(_execvp, execve): Provide prototypes.

* lib-src/emacsclient.c [WINDOWSNT]: Remove prototype for execvp,
it is now in nt/inc/ms-w32.h.
* lib-src/ntlib.c (getppid): Avoid compiler warnings due to format
mismatch.
(sys_ctime): Remove, not used.
