I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master

define:

M_LIT(x) - Paste the type specific suffix onto the constant x.
|
|
M_MLIT(x) - Paste the type specific suffix used by the macro
|
|
constants in math.h, i.e M_PI or M_PIl.
|
|
M_PFX - The prefixed used by float.h macros like FLT_MANT_DIG.
|

M_SUF(x) - Paste the the type specific suffix used by functions
|
|
i.e expf expl exp.
|
|
FLOAT - Resolves to the C typename of M_TYPE.
|
|
CFLOAT - Resolves to the complex typename of M_TYPE.
|
|
M_STRTO_NAN - Resolves to the internal libc function which
|
|
converts a string into the appropriate FLOAT nan
|

value.
