[uclibc-ng-devel] [PATCH] uclibc: prevent warning about setting an unused variable

From: Frank Mehnert <frank.mehnert(a)kernkonzept.com> This variable is used either if __UCLIBC_HAS_FLOATS__ is defined or if __UCLIBC_HAS_GLIBC_DIGIT_GROUPING__ is defined. Instead of adding more complicated #ifdef magic, just mark this variable as possibly unused to satisfy the compiler.
