Bugfix
  * Fix handling of EOF against 0xff bytes and on platforms with
    unsigned chars.  Fixes a build failure on platforms where char is
    unsigned.  Fixes #3794.
programs/ssl: Fix incorrect EOF check in ssl_context_info.c In `read_next_b64_code()`, the result of fgetc() is stored into a char, but later compared against EOF, which is generally -1. On platforms where char is unsigned, this generates a compiler warning/error that the comparison will never be true (causing a build failure). The value will never match, with the function ultimately bailing with a "Too many bad symbols are detected" error. On platforms with signed char, EOF is detected, but a file containing a 0xFF character will causes a premature end of file exit of the loop. Fix this by changing the result to an int. Fixes #3794.
