Please, can someone tell me which is the appropiate branch to commit
my patch?
Please note that I am new to cvs.
I have checked out BISON-1_33 branch to create the patch below using
cvs command: co -r BISON-1_33 bison. Now I get the following errors:
cvs server: sticky tag `BISON-1_33' for file `bison/ChangeLog' is not a branch
cvs server: sticky tag `BISON-1_33' for file `bison/NEWS' is not a branch
cvs server: sticky tag `BISON-1_33' for file `bison/doc/bison.texinfo' is not a
branch
cvs server: sticky tag `BISON-1_33' for file `bison/src/files.c' is not a branch
cvs server: sticky tag `BISON-1_33' for file `bison/src/getargs.c' is not a
branch
cvs server: sticky tag `BISON-1_33' for file `bison/src/system.h' is not a
branch
when I try to commit my changes. I have read cvs.info docs about sticky tags
but I prefer not to experiment with the CVS tree.
A clear instruction what branch shall be checked out to apply the changes
will be greatly appreciated.
TIA,
Guerrero, Juan Manuel

+
+On DOS/Windows 9X systems the file name extensions of the output files,
+like @file{.tab.c}, that may be used depend on the file system in use.
+The plain DOS file system has limited file name length, does not allow
+the use of a set of certain illicit characters and does not allow more
+than a single dot in the file name.
+
+The DJGPP port of @code{bison} will detect at runtime if (LFN) long file name
+support is available or not. LFN support will be available in a DOS session
+under Windows 9X and successors. Windows NT 4.0 needs a special LFN driver
+(@file(ntlfn08b.zip) or later available at any simtelnet mirror in the /v2misc
+dir) for proper LFN support in a DOS session. If LFN support is available the
+DJGPP port of @code{bison} will use the standard POSIX file name extensions
+of the output files. If LFN support is not available, then the DJGPP port
+of @code{bison} will use DOS specific file name extensions.
