>Description:
gcc.dg/i386-387-1.c fails on cygwin with:
FAIL: gcc.dg/i386-387-1.c scan-assembler call sin
FAIL: gcc.dg/i386-387-1.c scan-assembler call cos
FAIL: gcc.dg/i386-387-1.c scan-assembler call sqrt
Inspection of the assembler shows lines "call _sin" etc
If this is the desired outcome then the scan-assembler
regex needs patching (below)
>How-To-Repeat:
bootstrap and run testsuite
>Fix:
