Adds two new external authors to etc/update-copyright.py to cover bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then updates copyright messages as follows: 1) Update cgen/utils.scm emitted copyrights. 2) Run "etc/update-copyright.py --this-year" with an extra external author I haven't committed, 'Kalray SA.', to cover gas testsuite files (which should have their copyright message removed). 3) Build with --enable-maintainer-mode --enable-cgen-maint=yes. 4) Check out */po/*.pot which we don't update frequently.

/* This is a compatible replacement of the standard C library's <ctype.h>

with the following properties:
|
|
|
|
- Implements all isxxx() macros required by C99.
|
|
- Also implements some character classes useful when
|
|
parsing C-like languages.
|
|
- Does not change behavior depending on the current locale.
|
|
- Behaves properly for all values in the range of a signed or
|
|
unsigned char.

|
|
To avoid conflicts, this header defines the isxxx functions in upper
|
|
case, e.g. ISALPHA not isalpha. */
