Thomas Quinot <quinot@act-europe.fr> * g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.ads: (C_Writev): Change MSG_Forced_Flags to Constants.MSG_Forced_Flags as there is no use of GNAT.Sockets.Constants. Remove remaining pragma Import for C_Write Remove C_Read and C_Write from internal implementation unit GNAT.Sockets.Thin, as their usage for sockets is non-portable (using the read and write functions from the system runtime library is fine on UNIX but won't work under Windows). * g-socket.adb: (Abort_Selector): Use C_Send instead of C_Write. (Check_Selector): Use C_Recv instead of C_Read. Selectors are the GNAT.Sockets abstraction to perform a select() call on a set of descriptors. To allow abortion of an ongoing select operation, some data is written to a dedicated socket that is always monitored. Under Windows, the write and read library functions cannot operate on sockets, so we need to use send and recv instead, which is portable across all supported platforms. * g-socthi.ads: Remove C_Read and C_Write from internal implementation unit GNAT.Sockets.Thin, as their usage for sockets is non-portable (using the read and write functions from the system runtime library is fine on UNIX but won't work under Windows).

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
