Subject: sim: sh: fix isnan redefinition with mingw targets
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=697fa6fe670d20403c63de0746aaa6a706c7ca3b;p=binutils-gdb.git

sim: sh: fix isnan redefinition with mingw targets

The code assumes that all _WIN32 targets are the same and can
define isnan to _isnan.  For mingw targets, they provide an isnan
define already, so no need for the fallback here.
