# Starting version 1.17, libiconv uses the version of gnulib that implements a

# configure-time check for C compiler flags that enables/disables certain warning
|
|
# (see https://git.savannah.gnu.org/gitweb/?p=gnulib.git;h=0c8a563f6). Unfortunately, the
|
|
# check does not work for compilers that inject extra symbols into the translation unit
|
|
# during the preprocessing step. For example, NVHPC injects the definition of the
|
|
# __va_list_tag structure, which appears verbatim on the compilation command line as
|
|
# additional compiler flags. The easiest way to circumvent the issue is to make the
|
|
# configure script believe that the compiler does not support a flag that allows warnings:
