[tex-live] update on "nasty pdf(la)tex bug on Solaris SPARC with ZFS"

[Thanh Han The]

I don't have a fix yet, just some more info: it's very
likely that the problem is caused by inconsistent
declaration of type longinteger. Tracing it down is not
easy due to nested inclusion of header files, however a
quick check can be done in gdb as follows:

,--------
| info type longinteger
|
| All types matching regular expression "longinteger":
|
| File pdftexini.c:
| typedef long long int longinteger;
|
| File pdftex0.c:
| typedef long long int longinteger;
|
| [...many files with the same declaration of longinteger...]
|
| File ../../../../src/texk/web2c/pdftexdir/writejbig2.c:
| typedef long int longinteger;
|
| File ../../../../src/texk/web2c/pdftexdir/pdftoepdf.cc:
| typedef long int longinteger;
`--------

Note that the last 2 declarations are "long int" and not "long long int"

longinteger is defined in web2c/config.h as off_t, which also has inconsistent
declaration over different files: like longinteger, it's "long long int" for
most files, except the following:

,--------
| File ../../../../src/libs/xpdf/goo/gfile.cc:
| typedef long int off_t;
|
| File ../../../../src/texk/web2c/pdftexdir/pdftoepdf.cc:
| typedef long int off_t;
`--------
