How to profile cygwin1.dll.

The hard way:

Build libc.a and libm.a with -pg.
Build all the cygwin1.dll source - except mcount.c - with -pg and no -O2.
-O2 interferes with -pg in some inlined code.
Link libgmon.a into cygwin1.dll.
build cyggmon.dll and copy to /usr/bin.

I used a CCNOPROF target in Makefile.in to make this relatively easy.

The gmon code must be in a dll, so that multiple .dll's all built with profiling will all access the same instance of _gmonparam. The result if this is not done is that only the code in .a and .o items gets recorded to the gmon.out file.

Voila.
