Subject: Patch for building tz on HP-UX (FILENAME_MAX)


Hello,

First let me say thanks, tz appears to be an incredibly useful library.

However after building on HP-UX (details below) I ran into a problem with
the definition of FILENAME_MAX. As HP-UX still supports some of its older
filesystems the longest guaranteed FILENAME is 14 characters. This gives a
FILENAME_MAX value that is too short to access most of the timezone location
files.

	OS: HP-UX 11
	cpp.ansi: HP92453-01 B.11.11.06 HP C Preprocessor (ANSI)
	ccom: HP92453-01 B.11.11.04 HP C Compiler
	/usr/ccs/bin/ld: 92453-07 linker linker ld B.11.30 011005

Patching tz, to optionally build with longer filename support can be done in
any number of ways. One such change to support a new Makefile option
"TZ_FILENAME_MAX" is described in the following patch/diff
output:

And finally how can I subscribe to this mailing list?
