2.5.31: unprotected uint32_t usage in flex.skl

[Hans-Bernhard Broeker]

Hello, flexers,

I can only hope I'm not getting on your nerves with all these...

Here's the next stumbling block in my experiments with the flex-2.5.31
snapshot: 'make check' fails to compile test-multiple-scanners-r, because
of references to undefined type uint32_t in flex.skl:

flex.skl:    uint32_t bread; /**< bytes read since beginning of current tableset
flex.skl:    if (fread (v, sizeof (uint32_t), 1, rd->fp) != 1){
flex.skl:    *((uint32_t *) v) = ntohl (*((uint32_t *) v));
flex.skl:    rd->bread += sizeof(uint32_t);

Once I changed theses, the rebuild of skel.c triggered by this failed
in an out-of-source-directory build setup: it rebuilt $(builddir)/skel.c
instead of $(srcdir)/skel.c, and failed to find several included files:

stdin:176: /usr/local/bin/gnum4: Cannot open flexint.h: No such file or 
directory
stdin:1074: /usr/local/bin/gnum4: Cannot open tables_shared.h: No such file or 
directory
stdin:2865: /usr/local/bin/gnum4: Cannot open tables_shared.c: No such file or 
directory

I fixed that temporarily by editing the special rule in Makefile.am for
skel.c to

        ( cd $(srcdir) ; ...all the action...)

(and removing all $(srcdir)/ prefixes from the command itself)
