The reason is simple, src:libjpeg-turbo started to use FILE in its
jpeglib.h header without including stdio.h first. See the minimal
reproducer (similar to what vice configure script tries to find out if
jpeglib.h is present) below.
-- jpegtest.c --
#include <stddef.h>
#include <jpeglib.h>
int main(void) {
return 0;
}
-- jpegtest.c --
When you try to compile it with 'gcc -Wall jpegtest.c -o jpegtest' you get:
In file included from jpegtest.c:2:
/usr/include/jpeglib.h:916:52: error: unknown type name ‘FILE’

If I put '#include <stdio.h>' into jpeglib.h after the JPEGLIB_H
definition (ie, to line twenty) that fixes this problem.
