Subject: cppfiles.c (INO_T_EQ): Handle UWIN.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b27d2bd5fe27c1ef2f8f696b95a7dbed0fdffc60;p=gcc.git

cppfiles.c (INO_T_EQ): Handle UWIN.

        * cppfiles.c (INO_T_EQ): Handle UWIN.
        * c-common.c (decl_attributes): Flag unrecognized attribute
        functions as warnings instead of as errors.
        Support for i386-pc-uwin.
        * i386/uwin.h: New file.
        * i386/xm-uwin.h: New file.
        * i386/t-uwin: New file.
        * i386/uwin.asm: New file.
        * configure.in (i[3456]86-*-uwin*): Define.
        Add Workaround for vfork bug when hosted on uwin.
        * configure: Regenerate.
        * cccp.c (INO_T_EQ): Undefine. UWIN has inodes.
        (absolute_filename): UWIN uses POSIX pathnames only.
        * libgcc2.c (getpagesize): Do not define for UWIN.
        (mprotect): Likewise.
        * protoize.c (dirent.h): Conditionally include.
        (fputc): Prototype only if it's not a macro.
