Package texlive fails to build with GCC 14 on i586 (and probably othr 32bit
architectures too) because of various C99 violations which previously just
generated warning s but which cause errors with GCC 14 by default (see meta
bug#1220571).

The (first) problem stopping the build is:

pdftexini.c: In function 'loadfmtfile':
pdftexini.c:4016:25: error: assignment to 'boolean *' {aka 'int *'} from
incompatible pointer type 'internalfontnumber  ' {aka 'long int *'}
[-Wincompatible-pointer-types]
 4016 |     pdffonthasspacechar = xmallocarray ( internalfontnumber , fontmax )
;
      |                         ^
pdftexini.c: In function 'mainbody':
pdftexini.c:5569:27: error: assignment to 'boolean *' {aka 'int *'} from
incompatible pointer type 'internalfontnumber  ' {aka 'long int *'}
[-Wincompatible-pointer-types]
 5569 |       pdffonthasspacechar = xmallocarray ( internalfontnumber , fontmax
) ;
      |                           ^

so IIUC double the necessary size is allocated rater than just half but it
looks like a genuine type issue.  We can work-around the issue by building with
-Wno-error=incompatible-pointer-types (on 32 bit architectures) but it is
always better to fix these issues.

I admit that so far I am super puzzled where the file texk/web2c/pdftexini.c
comes from (or rather how it is generated?) so I'd be grateful if someone who
knows the package better looked at this.
